Heating the fiber to increase the polymer chain mobility often results in relaxation of the oriented molecules leading to degradation of fiber-axis properties. An alternative way is to use covalent, hydrogen and van der Waals interactions, or mechanical interlocking at the fiber–matrix interface. The properties of the fiber–matrix interface are of great importance for the macroscopic mechanical properties of composite materials. The two-dimensional interphases or finite-thickness interphases are considered when analyzing the interaction between fibers and matrix in composites. Polymer matrix is the continuous phase in the composites used to hold the reinforcing agent in its place, and its properties determine most of the degredative processes (delamination, impact damage, chemical resistance, water absorption, and high-temperature creep).

Plastics are the most common form of marine debris. They can come from a variety of land and ocean-based sources; enter the water in many ways; and impact the ocean and Great Lakes. Once in the water, plastic debris never fully biodegrades. Oceans are choking on plastic junk—millions of tones of water bottles, soda bottles, drinking straws and single use plastic bags.

Composite materials are generally used for buildings, bridges, and structures such as boat hulls, swimming pool panels, racing car bodies, shower stalls, bathtubs, storage tanks, imitation granite and cultured marble sinks and countertops. They are also being increasingly used in general automotive applications. A composite material is a combination of two materials with different physical and chemical properties. When they are combined they create a material which is specialized to do a certain job, for instance to become stronger, lighter or resistant to electricity. They can also improve strength and stiffness. Composite materials are particularly attractive to aviation and aerospace applications because of their exceptional strength and stiffness-to-density ratios and superior physical properties. A composite material typically consists of relatively strong, stiff fibers in a tough resin matrix.

Recycling also conserves resources and protects the environment. Environmental benefits include reducing the amount of waste sent to landfills and combustion facilities; conserving natural resources, such as timber, water and minerals; and preventing pollution by reducing the need to collect new raw materials. By reducing wastes, recycling also conserves natural resources, protects natural ecosystems, and encourages biological diversity, all of which enhance the long run sustainability of the biosphere. Waste is simply energy that has been transformed, but not used, in the process of doing something useful. Sustainability in their use phase is often a key driver for the selection of composites over traditional materials. Composite structures deliver a long service life combined with low maintenance requirements, and lightweight composites result in lower energy consumption throughout a product's life.

Rheometry is a critical research and development tool that helps Nye chemists and engineers better understand and characterize the properties of our existing products so that we can more precisely recommend ones that are likely to meet a customer's specific needs. In a Newtonian fluid, the relation between the shear stress and the shear rate is linear, passing through the origin, the constant of proportionality being the coefficient of viscosity. In a non-Newtonian fluid, the relation between the shear stress and the shear rate is different. Food rheology is the study of the rheological properties of food, that is, the consistency and flow of food under tightly specified conditions. Rheological characterization tools, such as viscometers, allow drug producers to directly affect how a drug is formulated and developed, cutting across parameters and conditions to arrive at product characteristics that can be quantified.

Ceramic matrix composites (CMCs) are a special type of composite material in which both the reinforcement (refractory fibers) and matrix material are ceramics. In some cases, the same kind of ceramic is used for both parts of the structure, and additional secondary fibers may also be included. Composites are usually classified by the type of material used for the matrix. The four primary categories of composites are polymer matrix composites (PMCs), metal matrix composites (MMCs), ceramic matrix composites (CMCs), and carbon matrix composites (CAMCs). The most common type are polymer matrix composites. They are produced in the largest quantities, due to their good room temperature properties.

Homo- and copolymers of polyamides, polyesters, polyanhydrates, poly (ortho esters), poly (amido amines), and poly (β-amino esters) are the important biomedical polymers which are hydrolytically degradable. These are also called biopolymers and smart polymers which are mainly used in biotechnology and medicine Broad spectrums of polymers; natural polymers, synthetic polymers, organic polymers as well as silicones are used in a wide range of cosmetic and personal care products as film-formers, emulsifiers, thickeners, modifiers, protective barriers, and as aesthetic enhancers. Polymers & materials for the biomedical field. Synthetic polymers have been used for many years in the biomedical field because of their valuable and adjustable characteristics such as biocompatibility, biodegradability, good mechanical properties, etc.

Although biodegradable and compostable plastics are technically recyclable, they are currently not recycled back into plastic material. Rather, they are treated as an impurity in the recycling of conventional plastics when collected together.

A synthetic emulsion polymer is a milky liquid that is used to manufacture many products we encounter every day. From barrier coatings on food wrappers to the pressure-sensitive adhesive of a sticky note to the liquid applied waterproofing membrane under shower tiles, these polymers are ubiquitous. Emulsion polymerization is a free-radical polymerization in which a monomer or mixture of monomers is polymerized in an aqueous surfactant solution to form a latex Emulsion polymerization is a unique process involves emulsification of hydrophobic monomers by oil-in water emulsifier, then reaction initiation with either a water soluble initiator.

Polymer scientific experts' examination huge, complex atoms (polymer) that are upgrade from numerous more modest (sometimes repeating) units. They concentrate how the more modest structure blocks (monomers) fuse, and make helpful materials with explicit attributes by controlling the sub-atomic construction of the monomers/polymers utilized, the synthesis of the monomer/polymer solidification, and applying substance and preparing procedures that can, generally, influence the properties of the end result. Polymer scientific experts are diverse inside the science local area in light of the fact that their comprehension of the connection among construction and property ranges from the sub-atomic scale to the perceptible scale. 

Polymer Technology have recasted the department of material science increasing the use of polymer-based substances from building materials to Packing materials, Fancy decoration articles, Electrical engineering, Communications, Automobile, Aircraft's, etc. Polymer Technology carved a niche in the fields of electronics and electrical materials, textiles, aerospace industry, automobile industry, etc. She has been able to tailor the industry needs to suit the specifications provided. 

In application prospects and performance characteristics and in property range and diversity, polymers offer novelty and versatility that can hardly be matched by any other kind of materials. Polymers are huge macromolecules composed of repeating structural units called monomers. Polymer developments not only include synthesis but also its structural –functional relationship, polymer bio conjugation, and novel polymerization methods. In Polymerization, many monomers are joined together in a chemical reaction to form macromolecules of different sizes and shapes. Polymers are popular in everyday life - from plastics and elastomers on the one side to natural biopolymers such as DNA and proteins on the other hand. 

Polymers have gone from being cheap substitutes for natural products to providing high-quality options for a wide variety of applications. Further advances and breakthroughs supporting the economy can be expected in the coming years. Polymers are derived from petroleum, and their low cost has its roots in the abundance of the feedstock, in the ingenuity of the chemical engineers who devised the processes of manufacture, and in the economies of scale that have come with increased usage. Polymers constitute a high-value-added part of the petroleum customer base and have led to increasing international competition in the manufacture of commodity materials as well as engineering thermoplastics and specialty polymers.

In a traditional pharmaceutics area, such as tablet manufacturing, polymers are used as tablet binders to bind the excipients of the tablet. Modern or advanced pharmaceutical dosage forms utilize polymers for drug protection, taste masking, controlled release of a given drug, targeted delivery, increase drug bioavailability, and so on and so forth.  Polymers have found application in liquid dosage forms as rheology modifiers.They are used to control the viscosity of an aqueous solution or to stabilize suspensions or even for the granulation step in preparation of solid dosage forms. Major application of polymers in current pharmaceutical field is for controlled drug release. In the biomedical area, polymers are generally used as implants and are expected to perform long-term service. This requires that the polymers have unique properties that are not offered by polymers intended for general applications. In general, the desirable polymer properties in pharmaceutical applications are film forming (coating), thickening (rheology modifier), gelling (controlled release), adhesion (binding), pH-dependent solubility (controlled release), solubility in organic solvents (taste masking), and barrier properties (protection and packaging).

A biomaterial is any substance that has been engineered to interact with biological systems for a medical purpose - either a therapeutic (treat, augment, repair or replace a tissue function of the body) or a diagnostic one. They may be of natural origin or synthesized in a laboratory. Advanced polymeric biomaterials proceed to serve as a cornerstone of new scientific applied sciences and therapies. The good sized majority of these materials, each natural and synthetic, interact with biological depend besides direct digital communication. However, biological systems have evolved to synthesize and employ naturally-derived materials for the technology and modulation of electrical potentials, voltage gradients, and ion flows. Bioelectric phenomena can be interpreted as strong signaling cues for intra- and inter-cellular communication. These cues can serve as a gateway to link artificial units with biological systems. Specific focal point will be granted to the use of natural and synthetic biological substances as necessary aspects in applied sciences such as thin film electronics, in vitro cell culture models, and implantable medical devices. Future views and emerging challenges will also be highlighted. Biomedical applications, polymers with good biological compatibility (such as Teflon) are also considered as biomaterials, and though, strictly, they are not biopolymers, they will be treated as biomaterials in this chapter. In this way we are led to consider the electret properties of artificial polymers such as Teflon and polysulfonate films which are of importance for biological or medical applications.
