In vitro degradation of the copolymer crosslinked with MMA is relatively more than that of NVP and the degradation decreases with an increase in the amount of the HA filler. Conducting polymers, such as polypyrrole (PPy), polyaniline (Pani), polythiophene (PTh) and their derivatives, have been used as the active layers of gas sensors. 9. Wei et al. An electric field potential of 7–8 kV was found optimal for the formation of the fibers, which were characterized using scanning and transmission electron microscopy techniques combined with attenuated total reflectance infrared spectroscopy and contact angle measurements. These are safe, less toxic and comparatively simple. Science and applications of biorelated polymers require people of different disciplines and scien-tific domains.

The term polymer … This   property can be utilized in generating pass words where high security is required. • These small units are repeated throughout the macromolecule chain. Mechanical and physical properties can be improved by the inclusion of nanoparticles and the method of preparation. The quality of the air that we breathe in our bodies is very important Issue and is a real concern of modern society. Conducting polymers (CPs) are a special class of polymeric materials with electronic and ionic conductivity. The polymeric materials waste management and the sustainability of biodegradable polymers are specified. In order to achieve greater exfoliation and dispersion of the hybrid nanofillers in the PEVA matrix, the pre-dispersing and destabilization technique was applied to the O-MMT and Bent, respectively. As observed from the study, it can be shown that an increase in thermal conductivity and viscosity resulted in increase in resistance to deformation of the material, while an increase in the material stiffness, resulted in increase in the rate of deformation and relaxation. The interesting aspects  of these   materials is that they can remember configuration and can confirm when exactly     same stimulus is given. Polymers make up many of the materials in living organisms, and … The SEM micrographs of the copolymer nanocomposites reveal a serrated structure reflecting higher mechanical strength, good dispersion, and good interfacial bonding of HA in the polymer matrix.

Application and Processing of Polymers … In a multitude of biomedical applications, the most and versatile class of biomaterials being applied broadly is represented by polymers [2]. The SEM analysis showed that the PEVA hybrid nanocomposite with 4OMMT: 1Bent had greater matrix deformation than the neat PEVA when subjected to tensile load. So, these are environmentally safe and non toxic. This chapter contains sections titled: Introduction Desired Properties of Polymers for Biomedical Applications Natural Polymers Synthetic Polymers Conclusion Acknowledgements Conflicts of Interests. This mechanical deformation could be related to the increased flexibility of the PEVA chains which facilitated more energy absorption during the stretching of the material. Bio-polymeric materials are currently being considered as an alternative option due to the inherent properties such as high strength-to-weight ratio, biodegradability, renewability, biocompatibility and cost-effectiveness. Among these are silk, cotton, starch, sand, and asbestos, as well as the incredibly complex polymers known as RNA (ribonucleic acid) and DNA (deoxyribonucleic acid), which hold genetic codes. interaction or contact with the human body; for these reasons, it must be non-toxic, biodegradable, biocompatible and meet, , basic properties which are found in nature that are r, develop materials that will meet all the requirements mentioned, Materials with super hydro phobic surfaces ar, to be very tough to wet.
