Superhydrophobic surfaces show attractive anti-icing properties. However, it remains a challenge for them to achieve icephobicity and ultralow ice adhesion in a humid environment, which is fundamentally attributed to the icing behavior on their hierarchical textures. Here, we address the issue by integrating a superhydrophobic copper mesh with an intelligent organogel that can secrete antifreezing agent autonomously in response to temperature. The antifreezing agent is composed of ethylene glycol and water. By autonomously secreting the antifreezing agent at subzero temperatures, the hybrid surface effectively inhibits the frosting process on the hierarchical texture of the superhydrophobic mesh. Consequently, the surface not only exhibits excellent antifrosting properties in a humid atmosphere but also repeatedly removes the ice deposited spontaneously due to ultralow ice adhesion (8 Pa). This integration of intelligent organogel paves a new and promising avenue to design superhydrophobic surfaces with excellent icephobic properties.

智能防冰表面，具有自除冰功能

超疏水表面显示出诱人的防冰性能。然而，对于它们而言，在潮湿环境中实现憎冰性和超低冰粘附仍然是一个挑战，这从根本上归因于其分层纹理上的结冰行为。在这里，我们通过将超疏水性铜网与智能有机凝胶相结合来解决该问题，该有机凝胶可以根据温度自动分泌抗冻剂。防冻剂由乙二醇和水组成。通过在零以下的温度下自主分泌抗冻剂，混合表面可以有效地抑制超疏水网状结构的分层结霜过程。所以，该表面不仅在潮湿的气氛中表现出优异的防霜性能，而且由于超低的冰附着力（8 Pa）而反复去除自发沉积的冰。智能有机凝胶的这种集成为设计具有出色的憎冰特性的超疏水表面铺平了一条新的有希望的途径。
