摘要:
采用溶胶-凝胶法,以正硅酸四乙酯(TEOS)和甲基三乙氧基硅烷(MTES)为前驱体,利用浸渍提拉法镀膜,经60 ℃烘干2 h制得疏水SiO2薄膜。研究MTES与TEOS摩尔比、乙醇加入量、加水量对薄膜疏水性能的影响。采用傅里叶变换红外光谱仪(FT-IR)、X线衍射仪(XRD)、接触角分析仪对薄膜的性能和结构进行表征。结果表明:制得的薄膜含有大量的—CH3,具有良好的疏水性; 薄膜呈非晶态结构。当n(MTES)/n(TEOS)=2、n(H2O)/n(MTES+TEOS)=2、n(乙醇)/n(MTES+TEOS)=4时,薄膜疏水性最好,与水的接触角达到128°。
Abstract:
Hydrophobic SiO2 thin films were prepared by a dip-coating method via 2 h drying on 60 ℃,with a sol-gel method using tetraethylorthosilicate(TEOS)and methyltrimethoxysilane(MTES)as precursor.The effects of the content of the molar ratios of MTES to TEOS,ethanol content and water content on hydrophobicity were inverstigated.Fourier transform infrared spectroscopy(FT-IR),X-ray diffraction(XRD),and contact angle measurement were used to characterize the properties and the structure of SiO2 thin films.Results showed that the thin films with lots of methyl had good hydrophobicity,and the thin films possessed amorphous structure.The thin films had the best hydrophobicity and the water contact angle was 128°, when n(MTES)/n(TEOS)=2,n(H2O)/n(MTES+TEOS)=2,n(ethanol)/n(MTES+TEOS)=4.
