摘要： 针对人工合成的超疏水材料机械稳定性差以及复杂工艺性问题，通过简单的溶胶-凝胶法（sol-gel）在硅橡胶表面原位生长二氧化钛,以制备高耐磨、柔性超疏水材料。制备的超疏水橡胶接触角达到1568°，可以在1 kPa压力下承受100次磨损循环后仍保持其超疏水性。此外，在硅橡胶中添加聚丙烯酰胺（PAM）吸水树脂，利用吸水树脂与TiO2的强相互作用，在橡胶表面构筑TiO2-PAM的微纳米粗糙结构，可以使硅橡胶超疏水表面的磨损寿命提升到200次循环。

Abstract: In view of the poor mechanical stability and complex processability of artificial superhydrophobic materials, a simple sol-gel method was used to have titanium dioxide (TiO2) particles in-situ “grown” from the surface of silicone rubber to prepare highly wear-resistant and flexible superhydrophobic materials. The contact angle of the prepared super-hydrophobic rubber reached 1568°, and its superhydrophobicity was maintained after 100 cycles of wear under a pressure of 1 kPa. Furthermore, the wear life of the superhydrophobic surface could be improved to 200 cycles after adding polyacrylamide (PAM), a water-absorbent resin, to silicone rubber compounds. A robust micro-nano rough structure of TiO2-PAM was built on the rubber surface by taking advantages of the strong interaction between PAM and TiO2 particles.
