Although superhydrophobic materials play important roles in emerging fields because of their anti-wetting behavior, they still face a series of challenges such as brittle rough structure. Herein, a mechanically durable superhydrophobic polymer material (SPM) with roughness-regenerative characteristics was synthesized by integrating acrylate-terminated polyurethane (A-PU) with precipitated silica particle (PSP) using vinyltriethoxysilane (VTES) as a bridge. With the optimization of UV curable components, the appropriate covalently cross-linking networks and hierarchical rough structure were formed in the polymer skeleton, endowing the SPM with solid mechanical strength (B hardness) and superior superhydrophobicity (CA>152°, SA<5°). Taking advantage of the roughness-regenerative characteristics across the material bulk, the SPM was capable of surviving after multi-cycle abrasion damages (>250 cycles). More importantly, the roughness-regenerative characteristics enabled the damaged SPM to repair its superhydrophobicity via sanding treatment (>40 cycles). Our findings convincingly propose a feasible approach to fabricate versatile superhydrophobic materials as promising candidates for emerging fields.

尽管超疏水材料由于其抗湿性能而在新兴领域中发挥着重要作用，但它们仍面临诸如脆性粗糙结构等一系列挑战。在此，通过使用乙烯基三乙氧基硅烷（VTES）作为桥，通过将丙烯酸酯封端的聚氨酯（A-PU）与沉淀的二氧化硅颗粒（PSP）集成在一起，来合成具有粗糙度再生特性的机械耐久性超疏水聚合物材料（SPM）。通过优化UV固化组分，在聚合物骨架中形成了适当的共价交联网络和分层粗糙结构，使SPM具有坚固的机械强度（B硬度）和优异的超疏水性（CA> 152°，SA <5° ）。利用整个材料块的粗糙度再生特性，SPM能够在多周期磨损损坏（> 250次循环）后幸存下来。更重要的是，粗糙度再生特性使受损的SPM能够通过打磨处理（> 40个循环）修复其超疏水性。我们的发现令人信服地提出了一种可行的方法来制造通用的超疏水材料，作为新兴领域的有前途的候选者。
