Despite the achievements in superhydrophobic surface obtained via geometrically uniform micro-nano scale surface texture, the mechanical robustness of superhydrophobic surfaces remains a challenge where service conditions involve solid-body contact. We introduce a unique sawtooth-ring protective microstructure design as an integrated shield for underlying superhydrophobic micro-pillar arrays. The sawtooth-ring design minimizes the areal occupancy of the surface and merges directly with the anti-wetting micro-pillar array, giving rise to an integrated micro-structure. The integrated surface micro-structure has been fabricated in an intermediate polymer mold via an innovative two-step thermal nanoimprinting process. The integrated sawtooth ring and micro-pillar array have been replicated on UV polymerized resin, thermally cured polydimethylsiloxane (PDMS) and solvent cast polycarbonate (PC) using the intermediate polymer mold. The post-compression water contact angle results demon...

具有嵌入式保护性锯齿环微结构的超疏水表面

尽管通过几何均匀的纳米尺度表面纹理获得了超疏水性表面的成就，但是在使用条件涉及到固体接触的情况下，超疏水性表面的机械强度仍然是一个挑战。我们介绍了一种独特的锯齿环保护性微结构设计，作为底层超疏水微柱阵列的集成屏蔽。锯齿环设计最大程度地减少了表面的占用，并与防潮微柱阵列直接合并，从而形成了集成的微结构。集成的表面微结构已通过创新的两步热纳米压印工艺在中间聚合物模具中制造。集成的锯齿环和微柱阵列已在UV聚合树脂上复制，使用中间聚合物模具进行热固化的聚二甲基硅氧烷（PDMS）和溶剂浇铸的聚碳酸酯（PC）。压缩后的水接触角表明...
