As a medical material, plastics should contain the following properties: no toxicity to the body, no carcinogenicity, no allergic reaction or interference with the body's immune mechanism; materials implanted in the body should have good biocompatibility; materials in contact with blood must have certain Anticoagulant properties; able to withstand the sterilization process without deformation. The application of plastics in medical treatment has shown a trend of continuous expansion. The innovation of new materials and processing technology has obviously become one of the important factors in the development of the industry.
Hydrogels are a typical class of soft and wet materials that have been used in many fields such as biomedicine, medicine, industry, and agriculture. Since the beginning of this century, the preparation, structure and properties of high mechanical strength hydrogels have gradually become a research hotspot.
A variety of hydrogels with excellent mechanical properties have been developed. Hydrogel-immobilized biomolecules and cells are also widely used in analysis and medical diagnosis. Specific to the medical device industry, a growing class of biomaterials in the industry is polymer hydrogels. These materials are natural or synthetic chemically crosslinked or physically crosslinked materials for a variety of applications in the medical device industry, including contact lenses, wound healing bandages, bone repair stents or catheters.
