季胺盐类抗菌聚合物穿透微生物细胞膜能力强,稳定性好,对皮肤刺激小,残余毒性低,被广泛认为具有良好且持久的抗菌性能。本文研究用马来酸酐,甲基丙烯酸二甲基氨基乙酯,甲基丙烯酸叔丁基氨基乙酯通过自由基聚合物法合成抗菌聚合物PTDM,并利用马来酸酐的架桥作用将三元共聚物PTDM牢固接枝在脱胶生丝表面,制备出具有高效安全的抗菌生丝,并对该抗菌生丝进行抗菌性能表征。 Quaternary ammonium salt antibacterial polymers penetrate microbial cell membrane ability, good stability, small skin irritation, low residual toxicity, is widely believed to have good and lasting antibacterial properties. In this paper, the use of maleic anhydride, dimethylaminoethyl methacrylate, t-butylaminoethyl methacrylate synthesis by free radical polymerization of polymer PTDM, and the use of maleic anhydride bridge will ternary The copolymer PTDM was firmly grafted onto the surface of deinked raw silk to prepare antibacterial raw silk with high efficiency and safety, and the antibacterial property of the antibacterial raw silk was characterized.
