摘　　要：首先利用CuSO_(4)/H_(2)O_(2)氧化体系将多巴胺(DA)快速聚合沉积在蚕丝织物上,再采用十二烷基三甲基硅氧烷(DTMS)修饰纳米TiO_(2),在蚕丝织物表面构建纳米级粗糙结构,并在表面引入长链硅烷疏水链,制备超疏水蚕丝织物。优化的DA快速聚合工艺为9 mmol/L CuSO_(4)、19.6 mmol/L H_(2)O_(2)、沉积时间60 min;优化的DTMS-纳米TiO_(2)整理工艺为0.6%纳米TiO_(2)、3.5 mL/L DTMS,烘焙温度105℃。制得的复合改性蚕丝织物静态接触角(CA)为156°,滚动角(SA)为5°,符合超疏水材料要求,且具有良好的自清洁能力和超疏水耐久性。Dopamine(DA)is rapidly polymerized and deposited on silk fabrics in the CuSO_(4)/H_(2)O_(2)oxidation system.Then,nano TiO_(2)is modified with dodecyltrimethylsiloxane(DTMS)to construct a nanoscale rough structure on the surface of silk fabrics.and long chain silane hydrophobic chains are introduced on the surface to prepare superhydrophobic silk fabrics.The DA rapid polymerization process is optimized as 9 mmol/L CuSO_(4),19.6 mmol/L H_(2)O_(2),deposition for 60 min.The DTMS-nano TiO_(2)finishing process is optimized as 0.6%nano TiO_(2),2.5 mL/L DTMS,baking temperature 105℃.The composite modified silk fabric has a static contact angle(CA)of 156°and a rolling angle(SA)of 5°,which meets the requirements of superhydrophobic materials and has good self-cleaning ability and superhydrophobic durability.
