definition of polymer material: macromolecular material, which is based on polymer compounds. Polymer materials are materials composed of compounds with relatively high molecular weight, including rubber, plastics, fibers, coatings, adhesives and polymer-based composites. Polymers are the forms of life. All living things can be regarded as a collection of polymers. Classification of polymer materials polymer materials are classified by source

polymer materials are classified into natural, semi-synthetic (modified natural polymer materials) and synthetic polymer materials by source. Natural polymers are the basis of the origin and evolution of life. Since the beginning of human society, natural polymer materials have been used as living and production materials, and their processing technology has been mastered. For example, silk, cotton and wool are used to make fabrics, and wood, cotton and hemp are used to make paper. In the late 1931s, semi-synthetic polymer materials appeared in the stage of chemical modification of natural polymers. The appearance of synthetic polymer phenolic resin in 1917 marked the beginning of human application of synthetic polymer materials. In modern times, polymer materials, like metal materials and inorganic nonmetal materials, have become important materials in science and technology and economic construction. Classification of polymer materials according to characteristics

Polymer materials are classified into rubber, fiber, plastic, polymeric adhesive, polymer coatings and polymer-based composite materials according to characteristics. ① Rubber is a kind of linear flexible polymer. The valence force between molecular chains is small, and the molecular chains are flexible. Under the action of external force, it can be deformed greatly, and it can be quickly restored to its original state after removing external force. There are two kinds of natural rubber and synthetic rubber. ② Polymer fibers are divided into natural fibers and chemical fibers. The former refers to silk, cotton, hemp, wool and so on. The latter is made from natural polymer or synthetic polymer through spinning and post-treatment. Fiber has high valence, low deformability and high modulus, and is generally a crystalline polymer. ③ Plastic is made of synthetic resin or chemically modified natural polymer as the main component, and then filler, plasticizer and other additives are added. Its intermolecular valence force, modulus and deformation are between rubber and fiber. According to the characteristics of synthetic resin, it is usually divided into thermosetting plastics and thermoplastic plastics; According to the purpose, it is divided into general plastics and engineering plastics. ④ polymeric adhesive is an adhesive material mainly made of synthetic natural polymer compounds. There are two kinds of natural and synthetic adhesives. Synthetic adhesives are widely used. ⑤ Polymer coatings are made of polymers as the main film-forming substances, and solvents and various additives are added. According to different film-forming substances, it can be divided into grease coatings, natural resin coatings and synthetic resin coatings. ⑥ Polymer-based composite material is a kind of composite material based on polymer compound and added with various reinforcing materials. It combines the performance characteristics of the original materials and can be designed according to the needs. Classification of polymer materials by use

Polymer materials are divided into ordinary polymer materials and functional polymer materials by use. Functional polymer materials not only have the general mechanical properties, insulation properties and thermal properties of polymers, but also have special functions such as conversion, transmission and storage of matter, energy and information. There are polymer information conversion materials, polymer transparent materials, polymer mimetic enzymes, biodegradable polymer materials, polymer shape memory materials and medical and medicinal polymer materials that have been applied. Performance of polymer materials The structure of polymer materials determines its performance. By controlling and modifying the structure, polymer materials with different characteristics can be obtained. Because of its unique structure and easy modification and processing, polymer materials have incomparable and irreplaceable excellent properties, which are widely used in science and technology, national defense construction and national economy, and have become indispensable materials in all aspects of modern social life. Many natural materials are usually composed of polymer materials, such as natural rubber, cotton, human organs and so on. The same is true of synthetic chemical fibers, plastics and rubber. Generally speaking, polymers that are widely used in life and have formed industrial production scale are general polymer materials, and those with special uses and functions are functional polymers. Synthesis and processing of polymer materials Before processing, polymer materials should be synthesized, and monomers should be synthesized into polymers for granulation, and then melt processing. The synthesis methods of polymer materials include bulk polymerization, suspension polymerization, emulsion polymerization and solution polymerization. Among them, initiator plays an important role. Azo initiator and peroxide initiator are both commonly used initiators, and polymer additives often have obvious effects on improving the performance and reducing the cost of polymer materials. Processing technology The processing and molding of polymer materials is not a simple physical process, but an important link that determines the final structure and properties of polymer materials. Except for adhesives and coatings, which can be used directly without processing and forming, rubber, fiber and plastic usually need to be processed into products by corresponding forming methods. The common forming methods of general plastic products are extrusion, injection, calendering, blow molding, compression molding or transfer molding. Rubber products have shaping processes such as plasticizing, mixing, calendering or extrusion. Fibers include spinning solution preparation, fiber forming and winding, post-treatment, as-spun fiber stretching and heat setting. In the process of molding, the polymer may be affected by the changes of temperature, pressure, stress and action time, which may lead to the degradation, crosslinking and other chemical reactions of the polymer, and change the aggregate structure and chemical structure of the polymer. Therefore, the processing process not only determines the appearance shape and quality of polymer products, but also has an important influence on the supramolecular structure, texture structure and even chain structure of materials.
