摘　　要：以正硅酸乙酯(TEOS)为前驱体经γ-氯丙基三乙氧基硅烷(CPTES)改性后制备硅溶胶,与以醇盐硝酸银(AgNO3)为前驱体制备的AgCl溶胶共混后形成复合溶胶,采用浸渍提拉法涂覆于PET基片表面形成SiO2-AgCl复合薄膜,采用SEM、FTIR、机械折叠、接触角测试、烘干质量法、贴膜法研究硅烷偶联剂含量对溶胶-凝胶成膜过程、成膜特性等的影响。结果表明,当摩尔比n(CPTES)∶n(TEOS)=1时可获得表面光滑膜厚均匀,具有良好膜基结合力、疏水性能、耐水性能及抗菌性能的SiO2-AgCl复合薄膜。Composite sol has been synthesized utilizing both silica sol with tetraethoxysilane （TEOS） as the precursor and modified by 3-chloropropyltriethoxysilane （CPTES） and AgCl sol with silver nitrate （AgNO3） as the precursor. The SiO2-AgCl composite films have been fabricated on PET samples through dip-coating method. The effect of Silane-coupling-agent concentration on surface properties has been investigated by using SEM,FTIR,Folding machinery,contact angle test,method of oven drying quality and so on. The results indicated that the composite films with n（CPTES）∶n（TEOS）=1 of the mol ratio possess uniform surface topography,good adhesion strength,hydrophobicity,resistance to water and antibiosis.
