Icing presents substantial economic challenges and endangers equipment safety. Contemporary anti-icing research emphasizes the integration of active and passive technologies, with a particular focus on mitigating ice adhesion for more efficient anti-icing and deicing solutions. In this study, a multilayer composite antideicing surface is developed, integrating energy storage, photo-/electro-thermal functionalities, and superslippery properties. The top quasi-solid slippery layer, composed of epoxy resin embedded with oil-stored graphene nanoparticles, provides stable hydrophobic performance for various water-based liquids, reducing ice adhesion to approximately 25 kPa. Furthermore, the energy storage layer at the base introduces heterogeneity in the icing timeline across regions, leveraging volumetric expansion during the water phase transition to disturb the ice interface, achieving adhesion reductions to around 12 kPa. The intermediate layer features photo-/electro-thermal capabilities, enabling surface temperature elevation upon application of electrical or optical energy, melting interfacial ice, and forming a liquid film. This process disrupts the frozen interface, further lowering the ice adhesion force to below 1 kPa. The synergistic interaction between photo-/electro-thermal effects and the superslippery surface significantly enhances the anti-icing and deicing efficiency of the composite structure. These findings offer promising advancements for engineering applications requiring high-efficiency active and passive anti-icing/deicing strategies.
结冰带来了巨大的经济挑战,并危及设备安全。当代防冰研究强调主动和被动技术的整合,尤其注重减轻冰附着力,以实现更高效的防冰和除冰解决方案。在本研究中,开发了一种多层复合防冰表面,集成了能量存储、光/电热功能和超滑特性。顶部的准固体滑层由嵌入储油石墨烯纳米颗粒 的环氧树脂组成,为各种水基液体提供稳定的疏水性能,将冰附着力降低至约25 kPa。此外,底部的能量存储层在不同区域的结冰时间线上引入了不均匀性,利用水相转变过程中的体积膨胀来扰乱冰界面,使附着力降低至约12 kPa。中间层具有光/电热功能,在施加电能或光能时可使表面温度升高,融化界面冰并形成液膜。这一过程破坏了冻结界面,进一步将冰附着力降低至1 kPa以下。光/电热效应与超滑表面之间的协同相互作用显著提高了复合结构的防冰和除冰效率。这些发现为需要高效主动和被动防冰/除冰策略的工程应用提供了有前景的进展。
