1.Biomedical polymers are abbreviated as medical polymers, which are a class of eye-catching functional polymer materials. It has penetrated into various fields of medicine and life sciences and applied to clinical diagnosis and treatment. Especially the so-called "biological materials" that are in direct contact with body fluids or can be implanted in the body, they must be non-toxic, have good biocompatibility and stability, have sufficient mechanical strength, and be easy to process and disinfect.

2.Biomedical polymer materials are polymers and composite materials of biomedical materials, also known as medical polymer materials. It can come from artificial synthesis or natural products. In addition to meeting general physical and chemical performance requirements, it must also meet biocompatibility requirements. Medical polymers can be divided into non-degradable and biodegradable types according to their properties. Non-degradable polymers include polyethylene, polypropylene, polyacrylate, aromatic polyester, polysiloxane, polyformaldehyde, etc., which are required to be stable in the biological environment for a long time without degradation, crosslinking or physical wear, etc. , And has good physical and mechanical properties. Although there is no absolutely stable polymer, it is required that it and its degradation products do not have obvious toxic side effects on the body, and the material does not cause catastrophic damage. Biodegradable polymers include collagen, linear aliphatic polyester, chitin, cellulose, polyamino acid, polyvinyl alcohol, polycaprolactone, etc., which can cause structural damage and performance degradation under the action of the ecological environment, and their degradation products can Through normal metabolism or absorbed by the body or excreted from the body, it is mainly used for drug release and delivery to carriers and non-permanent implant devices.

3. There are many types of medical polymer materials. From Tianling cover to toe bones, from internal organs to skin, from blood to facial features, there are artificial polymer substitutes. At the same time, polymer drugs and immobilized enzymes, artificial cells, labeled cells, immunoadsorbents, etc. are also developing rapidly. At present, as many as 8 million tons of medical polymer materials including medical supplies are produced in the world each year, valued at 3 billion U.S. dollars.
4.Polymer materials are widely used. Synthetic rubber, synthetic fibers, and plastics are all polymer materials. There are applications in communications, electronics, medical, chemical, aviation, aerospace and other fields. The most widely used in the chemical industry, latex, paint, etc. are all composed of polymer materials.
Coating is a layer of polymer material that is applied to the surface of industrial or daily products to play a beautiful or protective role. Commonly used industrial coatings include epoxy resin and polyurethane.
Fiber is another important application of polymer materials. Common synthetic fibers include nylon, polyester, acrylic polyester, aramid, polypropylene, etc.
5.Rubber can be divided into natural rubber and synthetic rubber. The main component of natural rubber is polyisoprene. The main varieties of synthetic rubber are butyl rubber, butadiene rubber, neoprene, EPDM, acrylate rubber, polyurethane rubber, silicone rubber, fluorine rubber and so on.
