摘要： 【目的】开发一种具有疏水自修复和防冰性能的表面。【方法】使用阳极氧化制备氧化钛多孔膜，并于膜孔中填充全氟聚醚，得到阳极氧化钛/全氟聚醚疏水表面。考察了阳极氧化钛/全氟聚醚疏水表面的疏水性、表面能、疏水自修复性、表面冰黏附应力等性能。【结果】与初始钛片相比，阳极氧化钛/全氟聚醚疏水表面具有较好的疏水性，表面能由 46. 5 J/m2降低至 15. 5 J/m2。在疏水表面氟化合物被破坏后，氧化钛多孔膜中负载的全氟聚醚会迁移到表面修复疏水性。当经过 4次等离子体破坏/修复循环后，表面水接触角为 96°，仍保持疏水状态。该表面的冰黏附应力由初始钛片的 0. 22 MPa降至 0. 06 MPa，具有较好的防冰性能。此外，该表面经过落砂冲击后，未发现明显的破坏和疏水性降低，具有较好的力学强度。【结论】阳极氧化钛/全氟聚醚疏水表面具有较好的疏水自修复、防冰性能，在疏水自清洁和防冰领域具有一定应用前景。

Abstract: ［Objective］ To develop of a surface with hydrophobic，self-healing and anti-icingproperties.［Methods］Porous titanium oxide films were prepared using anodic oxidation method andthe membrane pores were filled with perfluoropolyether to obtain an anodic titanium oxide/perfluoropolyether hydrophobic surface. The hydrophobicity，surface tension，self-healable hydrophobicityand ice adhesion of the composite coating were investigated.［Results］The results showed that the anodized titanium oxide/perfluoropolyether hydrophobic surface had better hydrophobicity compared tothe initial titanium sheet，and the surface energy of the composite coating decreased from 46. 5 J/m2 to
15. 5 J/m2. The perfluoropolyether loaded in porous titanium oxide migrated to the surface to repair thehydrophobicity，after the fluorine compounds were destroyed，which made it have self-healinghydrophobicity. After four plasma damage/healing cycles，the surface with a water contact of 96° remained hydrophobicity. The ice adhesion stress of the composite surface was reduced from 0. 22 MPa to 0.06MPa，which made it have good anti-icing performance. In addition，no obvious damage and decrease of hydrophobicity were found on this surface after sand abrasion，which made the surface have better physical and mechanical properties.［Conclusion］ The anodic titanium oxide/perfluoropolyethercomposite surface has good self-healable hydrophobicity and anti-icing properties，and has broad application prospects in the field of hydrophobic self-cleaning and anti-icing.
