Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a novel and efficient antibacterial PP composite material. Background technique [0002] Polypropylene (PP) is a translucent crystalline polymer with plasticity, odorless and non-toxic. Due to the regular structure and high crystallization of PP, the melting point can be as high as 167°C. It has good impact resistance at room temperature, heat resistance, corrosion resistance, and low density. It is currently the lightest general-purpose plastic. [0003] However, the existing composite materials prepared by polypropylene PP have poor antibacterial effect and unstable antibacterial, which easily lead to defects such as short service life and high economic investment. Contents of the invention [0004] (1) Solved technical problems [0005] The invention provides a novel high-efficiency antibacterial PP composite material, which has good antibacterial effect and stab...
