Ice accretion on airplane surfaces, power lines, or wind turbines can cause operational difficulties and disastrous events. Great efforts have been made to develop environmentally-friendly anti-icing or deicing surfaces over the last several decades, but a high-efficient, robust, and energy-saving surface for both anti-icing and deicing still remains a challenge. Herein, a sunlight-responsive and robust anti-icing/deicing coating is designed by integrating photothermogenic nanocarbon fibers with an amphiphilic material, which is based on hydrophobic polydimethylsiloxane (PDMS) and hydrophilic polyvinylpyrrolidone (PVP) segments. The resultant coating represents an excellent and energy-saving anti-icing/deicing performance: a 34-fold increase of freezing delay time compared with control steel and ∼18 KPa of ice adhesion strength enabling easy removal by a natural wind action, attributable to the intrinsic material properties (the ability of PVP to depress water freezing point and the low surface energy of PDMS). Moreover, nanocarbon fibers can further reduce the ice adhesion strength and endow the coating with a rapidly sunlight-sensitive photothermal deicing performance (up to 10°C/min), presenting the superiority of outdoor applications especially for high-altitude equipment and vehicles. After 30 icing-deicing cycle, simulated acid rain (pH = 0) scouring, sand dropping, and 200 abrasion cycle tests, this coating also exhibits an extraordinary durability and robustness. This work makes a promising anti-icing and deicing coating for a large-scale operation and practical applications in particular outdoors.

飞机表面，电源线或风力涡轮机上积冰可能会导致操作困难和灾难性事件。在过去的几十年中，人们一直在努力开发环保型除冰或除冰表面，但是高效，坚固且节能的除冰和除冰表面仍然是一个挑战。在本文中，通过将光热生成纳米碳纤维与基于疏水性聚二甲基硅氧烷（PDMS）和亲水性聚乙烯吡咯烷酮（PVP）链段的两亲材料整合，设计了一种对阳光敏感且坚固的防冰/除冰涂层。所得涂层代表了优异的节能防冰/除冰性能：相较于对照组钢，冻结延迟时间增加了34倍，冰附着强度达到〜18 KPa，可通过自然风轻易去除，这归因于其固有的材料特性（PVP能够降低水的凝固点和降低表面硬度） PDMS的能量）。此外，纳米碳纤维可以进一步降低冰的粘附强度，并使涂层具有对日光敏感的快速光热除冰性能（最高10°C / min），从而展现了户外应用的优势，尤其是对于高海拔设备和车辆。经过30次除冰除冰，模拟酸雨（pH = 0）冲刷，掉沙和200次磨损循环测试后，该涂料还具有非凡的耐久性和坚固性。
