摘要:
在常温常压下,以纳米炭粉为模板剂,利用正硅酸四乙酯(TEOS)在玻璃片表面进行化学气相沉积,经十六烷基三甲氧基硅烷(CTMS)改性处理制得超疏水透明涂层。采用静态接触角(CA)、傅里叶交换红外光谱仪(FT-IR)、紫外光谱仪(UV)、热分析仪(TGA)、交叉极化硅核磁共振谱仪(29Si CP MAS NMR)、X线光电子能谱仪(XPS)和透射电子显微镜(TEM)进行分析和表征。结果表明:TEOS的沉积时间对疏水涂层的接触角、滑动角及透光性均有一定的影响,最佳沉积时间为6 h,接触角高达166.1°,滑动角为2.1°,透光率达91%。此透明超疏水涂层具有极好的耐潮性能,即使暴露在室温环境中30 d,仍能保持良好的超疏水性能。
Abstract:
Highly transparent superhydrophobic coatings were prepared by tetraethoxysilane(TEOS)chemical vapor deposition(CVD)with charcoal powder as template, and cetyltrimethoxylsilane(CTMS)as treatment. The as-prepared films were characterized by static contact angle(CA), Fourier transform infrared spectrometry(FT-IR), UV-vis spectrum(UV), thermogravimetric(TGA), cross polarisation magic angle spinning 29Si nuclear magnetic resonance(29Si CP MAS NMR), X-ray photoelectron spectroscopy(XPS), and transmission electron microscopy(TEM). Results showed that the different deposition time had effects on water contact angle, sliding angle and transparency. The optimum performance film with deposition time 6 h exhibited superhydrophobicity(CA, 166.1° and SA, 2.1°)and high transparency(transmittance closes to 91%). In addition, the film showed excellent moisture resistance performance and maintained its superhydrophobicity against prolonged exposure to ambient conditions.
