AI Technical Summary

Problems solved by technology

[0003] However, the existing antibacterial polypropylene composite materials improve the antibacterial properties of the material by adding a certain amount of inorganic antibacterial agents or organic antibacterial agents. Among them, the compatibility between inorganic antibacterial agents and polypropylene is poor, so it will affect the antibacterial properties of polypropylene. The melt fluidity of the propylene composite material makes it difficult to process and shape; and the addition of organic antibacterial agents will affect the strength of the polypropylene composite material. Although the strength can be improved by adding an appropriate amount of reinforcing fibers, it will also reduce the polypropylene composite. Melt Fluidity of Propylene Composites

Therefore, further research on antibacterial polypropylene composite materials is needed to solve the problems of poor melt fluidity and low strength of existing antibacterial polypropylene composite materials
