The chemical component and morphology of the single-side highhydrophobic fSiO2/PES composite membrane was examined by ATR-FTIR, XPS, TEM and FESEM, individually. The effects of PFDTES modification amount and the heat treatment condition on membrane hydrophobicity were investigated, and the hydrophobic stability of fSiO2/PES composite membrane was evaluated. The results show that the water contact angle of the single-side highhydrophobic fSiO2/PES composite membrane is 131.5° when the mass ratio of PFDTES:TEOS is 3. The water contact angle of the single-side highhydrophobic fSiO2/PES composite membrane is 138.9°, as the heat treatment temperature is 100℃ and the heat treatment time is 4 h. In addition, the single-side highhydrophobic fSiO2/PES composite membrane exhibits excellent hydrophobic stable performance. 国家自然科学青年基金(51503146);河北省科技计划项目(13273707;16211243;18271238);河北省唐山市科技计划项目(14130238B;18130221a);唐山学院项目(hhx2018003 %K 聚醚砜 %K SiO2 %K 复合膜 %K 单侧 %K 高疏水
