摘　　要：本研究利用十甲基环五硅氧烷(D5)和纳米二氧化硅原位聚合后,用助剂γ-甲基丙烯酰氧基丙基三甲氧基硅烷(KH570)对聚合物改性,采用空气喷涂法在预处理玻璃表面上制取超疏水涂层。采用傅立叶红外光谱仪(FT-IR)、扫描电子显微镜(SEM)对其表面进行了表征;考察了涂层的热稳定性。结果表明:纳米Si O2粒子与D5开环产物成功复合;超疏水表面具有絮状的微纳二元复合结构,具有超疏水性能。耐热性分析显示,样品400℃处理后,仍然保持超疏水性;样品500℃处理后,Si-C共价键的断裂导致其超疏水性消失。D5/Si O2 was polymerized by decamethylcyclopentasiloxane（D5） and nano-silica in situ method, modified by additive of methacryloxypropyltrimethoxylsilane（KH570）. Superhydrophobic coatings were prepared on glass by air spraying method the in situ polymerization compositions over pretreated surface of glass. Coatings were systematically characterized by infrared spectrum（FTIR） and scanning electron microscope（SEM）. Its heat resistant property was detected. The results show that nano-silica and D5 opened ring successfully polymerize. The polymerization compositions possess with superhydrophobic property and bi-unit composite structure over micro-nano flocculation. Samples being heated at 400 ℃still maintained the superhydrophobic property by thermal analysis. Heated at 500 ℃, sample lost super hydrophobic due to Si-C covalent bond broken.
