摘　　要：用γ-氯丙基三甲氧基硅烷作活化剂,在纳米SiOx表面接枝高分子聚乙烯亚胺(PEI)长链,然后用卤代烷把PEI修饰成高分子季铵盐,制备具有抗菌功能的纳米SiOx。并对制备过程进行了优化。The nanometer SiOx with antibacterial activity was prepared by the process that long-chain high-molecular-weight polyethylenimine（PEI） was grafted on the surface of nanometer SiOx using γ-chloropropyl trimethoxy siloxane as a active agent, and then the PEI was modified by the alkyl halide as high-molecular-weight quaternary ammonium salts. At the same time, the process of preparations was optimized.
