先以甲基丙烯酸十八醇酯(SMA)、烯丙基缩水甘油醚(AGE)和含氢硅油(PHMS)的硅氢加成反应制得一种梳状结构的十八酯基/环氧基改性聚硅氧烷(PSAMS),再通过其与氨基功能改性纳米SiO2间的接枝共聚反应制备了一种改性聚硅氧烷/纳米SiO2杂化材料(PSAMS-SiO2).采用一次浸渍法,简便地在天然棉纤维表面制得对水的静态接触角达157°的改性聚硅氧烷/纳米SiO2杂化膜.用红外光谱(FTIR)、X射线光电子能谱(XPS)、热重分析仪(TGA)、扫描电子显微镜(SEM)、静态接触角测量仪等仪器研究了杂化材料的结构、热稳定性、膜微观形态和疏水性.TGA分析表明杂化材料的热稳定性明显提高；XPS和SEM观察证实了棉纤维表面的疏水杂化膜和大量仿荷叶效应的纳米微突体.随PSAMS-SiO2用量增加,膜超疏水性能提高.
