It is difficult to find an aspect of our lives that is not affected by polymers. Polymers are a highly diverse class of materials which are available in all fields of engineering from avionics through biomedical applications, drug delivery system, biosensor devices, tissue engineering, cosmetics etc. natural polymers:- the definition of a natural polymer is a polymer that results from only raw materials that are found in nature. the application of polymers and their subsequent composites is still advancing and increasing quickly due to their ease regarding manufacturing. Applications of Polymers. Such compounds may have metallic conductivity or can be semiconductors. Mao C, Liang C, Luo W, Bao J, Shen J, et al. Cyclic polymers are an intriguing class of polymers due to their lack of chain ends. recycled concrete, source unknown and difficult to directly measure its intensity of waste concrete materials, at the time of the preparation of recycled aggregate, it is recommended to repeat loading, using different pressures from different standard strength of recycled concrete coarse aggregate crushed curve to use as a criterion to determine the source of their overall strength. Therefore, it is a challenge to find a polymer that has all the required properties for high efficiency devices, such as strong and broad absorption, high carrier mobility, and appropriate energy levels. The main functions of biological adhesives and sealants are to repair injured tissues, reinforce surgical wounds, or even replace common suturing techniques. tional hybrid polymers or nanocomposites are accessible and have become important to achieve active optical functions, e.g. Conducting polymers of various forms will be electrodeposited onto oxidisable metals and electrochemical and environmental means will be used to access their applicably for corrosion protection. Polymer/metal nanocomposites consisting of polymer as matrix and metal nanoparticles as nanofiller commonly show several attractive advantages such as electrical, mechanical and optical characteristics. A tensile test was done to evaluate the mechanical properties of the resultant nanocomposites and to allow the selection of the best OMMT/Bent ratio for the production of the hybrid nanocomposite. 6. The word ‘polymer’ is coined from two Greek words: poly means many and mer means unit or part. reaching practical applications, because it has led to an understanding of how and why the physical and chemical properties of polymers change with the nature of the monomers from which they are synthesized.

An alternative and/or improved material for the energy sector is of major concern due to the advancement in the sector and the hazardous environmental impact of the current materials in use. These are safe, less toxic and comparatively simple. 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. Many modern objects use polymers in the form of thermoplastics as well as fibers. When the modified chitosan/polylactic complex braid was immersed in the simulated body fluid for 21 days, the overall hydroxyapatite was in sphere shape as previous studies had argued. Polymers in biomedical applications are: non-toxic, biodegradable, biocompatible and meet the required specification for which they are intended because it has direct contact with the human body.

In this study, simple beam tests proposed by Ichinose were carried out to estimate the bond performance of reinforced concrete beams with EAF oxidizing slag aggregates. This is another phenomenon that is exhibited by plants. Polymers have played indispensable roles in the preparation of pharmaceutical products. Polymers are one of the most important and enormously used materials in the modern society. Consequently, the analytical results considering the effect of transverse reinforcement showed reasonable agreement with the experimental results. biomedical applications. 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.
