采用旋涂法和喷涂法，通过溶胶-凝胶法在不同的金属和陶瓷基材上制备了二氧化钛和二氧化硅基憎水涂料。与旋涂涂料相比，喷雾涂料在室外环境中稳定的同时，能够再生超疏水，并保持自洁性能。旋涂涂层在水滴的冲击下表现出更强的机械抗性，并且几乎没有降低基材的光学透过率。二氧化硅涂层也比二氧化钛涂层具有更好的热稳定性，并且在6个月的室外环境中仍能保持防水性能(C)2016爱思唯尔公司版权所有。
TiO2 and SiO2 based water repellent coatings were prepared on various metal and ceramic substrates via spin and spray methods through sol-gel route. Compared to the spin coatings, the spray coatings were able to regenerate superhydrophobicity and to maintain self-cleaning properties while being stable in outdoor environment. The spin coatings appeared to be more mechanical resistant under the impact of water drops and barely reduced the optical transmittance of the substrate. The SiO2 coatings were also more thermal stable than the TiO2 ones and maintained the water repellent properties after 6 months of outdoor environment (C) 2016 Elsevier B.V. All rights reserved.
