【摘要】 为了减少有毒有机溶剂的使用,制备环境友好的水溶性超疏水材料。采用自由基聚合合成水性环氧树脂聚(甲基丙烯酸缩水甘油酯-无规-丙烯酸丁酯-无规-甲基丙烯酸羟乙酯（P（GMA-r-BA-r-HEMA））,经七氟丁酸（HFBA）与氨基纳米二氧化硅（SiO₂）杂化组装,以水为溶剂制备超疏水材料,在棉织物表面构筑超疏水表面。通过改变氨基纳米SiO₂的含量,探究棉织物的疏水性能和耐溶剂性能。研究结果表明,当接枝含氟量一定时,随着氨基纳米SiO₂含量的增加,超疏水处理棉织物的超疏水效果越好。经该超疏水材料浸渍改性的棉织物,有良好的疏液效果,水接触角为（150±2）°,耐久时间为83 min,具备很好的耐溶剂性,能耐受水洗涤、超声和NaCO₃溶液洗涤。更多还原

【Abstract】 In order to reduce the use of toxic organic solvents, environmentally friendly water-soluble superhydrophobic materials were prepared. Waterborne epoxy resin poly(glycidyl methacrylate-random butyl acrylate-random-hydroxyethyl methacrylate（P（GMA-r-BA-r-HEMA）） was prepared by radical polymerization heptafluorobutyric acid（HFBA） and nano-silica modified hybrid assembly, using water as solvent to prepare superhydrophobic materials, and superhydrophobic surface on cotton fabric surface. The hydrophobic properties and solvent resistance of cotton fabrics were investigated by changing the content of amino silica. The results show that the superhydrophobic effect of superhydrophobic treated cotton fabrics was better with the increase of amino silica content when the amount of grafted fluorine was constant. The cotton fabric impregnated with the superhydrophobic material had a good lyophobic effect, the water contact angle was（150±2）°, and the durability time was 83 min. It had good solvent resistance and could withstand water washing, ultrasonic and NaCO₃ solution washing.更多还原
