壳聚糖/银-铜复合抗菌剂的制备及在硅橡胶基体上的应用
Preparation of Chitosan/silver-copper Composite Antibacterial Agent and Its Application on Silicone Rubber Matrix
摘要
Abstract
In this paper ,Chitosan/Silver/Copper (CAC) antibacterial agent was prepared by chemical reduction ,an antibacterial polymer material of silicone rubber was obtained by grafting surface functional groups onto silicone rubber matrix .The sample was characterized by scanning electron microscopy (SEM ) ,transmission electron microscopy (TEM ) ,and X‐ray photoelectron spectroscopy (XPS ) .T he antibacterial activity of composite antibacterial agents and antibacterial materials was characterized by inhibition zones and shake flask tests . Finally , the conclusion was :the degree of microbial growth of CAC against E .coli and S .aureus is only 18% and 26% re‐spectively ,the initial decomposition temperature of CAC is about 70 ℃ higher than that of CS/Ag colloidal sol ,CAC antibacterial agent exhibits high antibacterial activities and thermal stability ;The preparation process for the antibacterial silicone rubber is simple and inexpensive ,the thick‐ness of antibacterial function layer is about 50‐70 μm ,the antibacterial ratio is above 96% for E . coli and S .aureus ,with excellent antibacterial activities .关键词
