摘　　要：以3-氨丙基三乙氧基硅烷(APTES)为原料,通过溶胶-凝胶法制备氨基改性纳米SiO2溶胶,经浸渍法在柠檬酸预处理棉织物表面包覆纳米SiO2,构造表面粗糙结构,再利用十六烷基三甲氧基硅烷(HDTMS)进行低表面能修饰,制得超疏水棉织物。实验测试整理前后试样的粒径、表面形貌、紫外防护、疏水性能及物理性能。结果表明:经氨基改性纳米SiO2溶胶整理的棉织物表面粗糙度大,利于构建超疏水层,在紫外防护、超疏水性和耐洗牢度方面更具优势。The 3-aminopropyltriethoxysilane(APTES)is used to prepare amino-modified nano-SiO2 sol by sol-gel method,and the surface of pretreated cotton fabric with citric acid is coated with nano-SiO2 by dipping method to construct a rough surface structure,and then the hexadecyl trimethoxy silane(HDTMS)is used for low surface energy modification to obtain a super-hydrophobic cotton fabric.The particle size,surface morphology,UV protection,hydrophobicity and physical properties of samples before and after modification are tested.The results reveal that the cotton fabrics finished with amino-modified nano-SiO2 sol have a much rougher surface to construct a super-hydrophobic layer and have more advantages on UV protection,super-hydrophobicity and washing fastness.
