What are the chemical materials?
Polymer is composed of carbon, hydrogen, oxygen, silicon, sulfur and other elements of the molecular weight of the organic compounds of high enough. Known as the polymer, because of its high molecular weight. Commonly used polymer molecular weight in a few hundred to several hundred The effect of high molecular weight on the nature of the compound is that it has a certain strength and can be used as a material, which is also a place where the polymer compound is different from the general compound, and because the polymer compound generally has a long chain structure, All the molecules are like a long line, many molecules together, it becomes a naked thread group, which is the polymer compounds with high strength, can be used as the structural material of the root causes.On the other hand, People can also be through a variety of means, with physical or chemical methods, or the interaction of macromolecules and other substances after the physical or chemical changes, so that the polymer compounds can become a special function of functional polymer materials.
Generally speaking, the polymer can be divided into natural macromolecules and synthetic (artificial) molecules.
Functional polymer materials mainly include the physical function of polymer materials and chemical function of polymer materials.The former are such as conductive polymer, polymer semiconductor, photoconductive polymer, piezoelectric and thermoelectric polymer, magnetic polymer, optical polymer, liquid crystal Polymer and polymer materials, etc .; the latter, such as reactive polymers, ion exchange resins, polymer separation membranes, polymer catalysts, polymer reagents and artificial organs, in addition to biological functions and medical polymer materials, Such as biopolymers, simulators, macromolecules and artificial bone materials.
Whether it is as a food protein or as a cotton fabric, wool and silk are natural polymer materials, even the body itself, basically also by a variety of biological polymers. China in the development of natural polymer materials have been walking The world's leading level. The use of bamboo, cotton, linen and other polymer materials such as fiber paper is one of the four ancient inventions in ancient China.In addition, the use of tung oil and large paint and other polymer materials as paint, paint paint products are ancient Chinese tradition technology.
