| 摘 要： | 针对含氟拒水剂不环保的缺点，采用无氟溶胶-凝胶法赋予棉织物疏水性能。先浸轧二氧化硅溶胶，再将烷烃硅氧烷自组装到棉织物上，成功制备了具有超疏水性能的棉织物。通过控制催化剂用量，制备不同粒径的二氧化硅溶胶，并讨论了溶胶粒径、烷基硅氧烷结构和浓度及皂洗次数对接触角的影响。采用这种方法整理后棉织物与水的接触角可达到155°。利用扫描电子显微镜观察二氧化硅溶胶整理前后棉织物的表面形态并对性能进行测试，结果表明整理前后棉织物的物理机械性能变化较小。

| Abstract: | The aim of this study is to prepare water repellent cotton fabric via sol-gel method using non-fluorinated additives,thus avoiding the potential risk for environment from fluoroalkyl compounds.Superhydrophobic cotton fabric was successfully obtained first by dip-coating the silica sol,then the fabric was modified with alkyltrialkoxysilanes through self-assembly methods.Silica sols with different sizes were prepared by controlling the concentration of ammonia.The influence of silica nanoparticle sizes,struct... |
