Problems solved by technology

[0004] The above-mentioned existing antibacterial polyester materials are always unsatisfactory, and there are some defects of one kind or another. On the one hand, the antibacterial agent doped by the physical blending method will gradually release over time, and the antibacterial performance is weakened so that it cannot be used. Achieve long-lasting antibacterial effect; on the other hand, antibacterial agents commonly used for surface modification such as metal ions, quaternary ammonium salts, and imidazole compounds often cannot meet the requirements of environmental friendliness, and the accumulation of dead microorganisms on the surface of the polymer will hinder the antibacterial function In addition, by releasing the bactericide antibacterial method, it not only destroys the harmful flora, but also may cause damage to the skin's own flora, which cannot satisfy good biocompatibility
