ABSTRACT=Fighting sports have an important position and value in modern sports. Traditional fighting sports equipment has poor antibacterial and flexible performance, and is difficult to provide stable support and protection for athletes. Traditional combat equipment typically uses synthetic materials such as polyurethane and synthetic leather. These materials have a certain degree of strength and durability, but their flexibility and antibacterial properties are poor. In order to enhance the antibacterial and flexibility of sports equipment and reduce the risk of athlete injury, this article conducted in-depth research on the development of fighting sports equipment using conjugated polymers. This article first selected polypropylene (PP) as the matrix material for fighting athletes’ sports equipment, and used gas phase polymerization to prepare the material. Then, chitosan was used as an antibacterial agent, and the oxidative degradation method was used to prepare it. The chitosan antibacterial agent was then applied to the prepared PP material, and the antibacterial treatment was carried out using a combination of impregnation and rolling. Finally, the structural design of the sports equipment was achieved by filling and combining the top equipment of fighting athletes using the spunbond melt blown composite method. To verify the effectiveness of the equipment, this article conducted equipment performance testing and sports injury simulation. The results showed that the average diameter of the antibacterial zone of the sports equipment in this article reached over 1 millimeter, and in the injury risk test, the average results of the reduction in joint and muscle injury risk of the wrestlers under the material equipment in this article were about 16.9% and 20.5%, respectively. The conclusion indicates that the development of fighting sports equipment based on conjugated polymers can help reduce the risk of athlete injury and improve the safety of fighting sports.
