In nature, lifetime-long functionalities of land plant leaves rely on the regenerability as well as the solid feature of the epicuticular wax layer. Inspired by the regenerable solid epicuticular wax on land plant leaf surfaces, herein a type of solid organogel material with regenerable sacrificial alkane surface layer is reported. This type of surface material is demonstrated to be of great practical importance for tackling solid deposition, such as anti-icing, antigraffiti, and antifouling, since the deposited foreign materials can be easily removed together with the alkane surface layer. Significantly, the solid alkane layer does not contaminate nearby surfaces due to its solid nature in both working and stand-by conditions, which is completely different to liquid-infused materials.
在自然界中，陆地植物叶片的终身功能依赖于再生能力和表皮蜡层的坚固特性。受陆地植物叶片表面可再生固体表皮蜡启发，本文报道了一种具有可再生牺牲烷烃表面层的固体有机凝胶材料。由于沉积的外来材料可以与烷烃表面层一起很容易地去除，因此这种表面材料对于解决固体沉积问题，如抗结冰、抗涂鸦和防污，具有非常重要的实际意义。重要的是，由于固体烷烃层在工作和待机条件下均具有固态，因此它不会污染附近的表面，这与液体注入材料完全不同。
