摘　　要：目前所制备的疏水疏油丝绸织物大多难以同时满足疏水疏油及耐洗性,或制备过程过于复杂。因此,文章提出在丝绸表面浸涂一层疏水改性的二氧化硅纳米粒子以提供一定的粗糙度,随之将聚(偏氟乙烯-六氟丙烯)溶液喷涂于其上以提供低表面能,两者的协同作用可使丝绸织物具有高度的疏水疏油性和良好的耐洗性能。结果显示,通过这一简单易实施的两步法,制备所得丝绸织物表面的水接触角高达149.5°、滚动角小至5.5°,色拉油的接触角可达132°,表现出高度的疏水疏油性。经20次标准洗涤后,水接触角仍在140°以上,且滚动角小于10°,表现出优异的耐洗色牢度。It is difficult for current hydrophobic and oleophobic silk fabrics to meet hydrophobic and oleophobic characteristics as well as washing durability at the same time,or the preparation process is too complex.Thus,in this study,we proposed to coat hydrophobic modified silica nanoparticles on the fiber surface to provide certain roughness,and then spray poly(vinylidene fluoride-hexafluoropropylene)(PVDF-HFP)to provide low surface energy.The synergistic effect of the two could make the silk fabric had high hydrophobic and oleophobic properties as well as good washing durability.The results indicated that via this simple two-step method,the prepared silk fabric presented a water contact angle(WCA)of 149.5°,a water sliding angle(WSA)of 5.5°,and an oil contact angle(OCA)of 132.0°,demonstrating the high hydrophobicity and oleophobicity of silk.After standard washing for 20 times,the WCA was still more than 140°and the WSA was less than 10°,showing excellent laundering durability.
