我们提出了一种制备由改性TiO2纳米粒子和聚硅氧烷树脂组成的全层超疏水复合涂层的简单方法。采用扫描电镜（SEM）、傅里叶变换红外光谱仪（FTIR）、接触角计和自制简易装置分别对改性后的TiO2纳米粒子和复合涂层的表面形貌、化学成分、接触角和滑动角进行了表征。结果表明：改性后的TiO2纳米粒子和制备的复合涂层的接触角和滑动角分别达到152°和0°；此外，由于涂层设计为全层超疏水性，复合涂层在热重分析（TGA）实验、磨损试验和浸没试验中也分别表现出良好的热稳定性、耐磨性和耐腐蚀性。
We present a simple approach for the fabrication of a full-thickness super-hydrophobic composite coating consisted of modified TiO2 nanoparticles and polysiloxane resin. Scanning electron microscope (SEM), fourier transform infrared spectrometer (FTIR), contact angle meter and a simple self-made device were employed to characterize the surface morphologies, chemical compositions, contact angle and sliding angle of the modified TiO2 nanoparticles and composite coating, respectively. Results show that for both the modified TiO2 nanoparticles and the as-prepared composite coating the contact angle and sliding angle of is up to 152 degrees and 0 degrees, respectively. In addition, due to the coating design of full-thickness super-hydrophobicity, the composite coating also exhibited good thermal stability, abrasion resistance and corrosion resistance in the thermo-gravimetric analysis (TGA) experiment, abrasion test and immersion test, respectively.
