Slide-ring crosslinked polydimethylsiloxane (PDMS) is designed and prepared for anti-icing/deicing applications. Compared with the covalent crosslinks, the slidable crosslinks enhance the mobility of polymer networks and endow the materials with low elastic modulus. The PDMS matrix guarantees the hydrophobicity of as-prepared coatings. These properties synergistically lead to ultra-low ice adhesion strength (13.0 ± 1.3 kPa) and excellent mechanical durability. The ice adhesion strength on the coating maintains a value of ∼12 kPa during 20 icing/deicing cycles, and increases gradually to a value of ∼22 kPa after 800 cycles of abrasions. The novel design strategy provides one-step forward to anti-icing/deicing solutions for targeted applications.
滑环交联聚二甲基硅氧烷（PDMS）专为防冰/除冰应用而设计和制备。与共价交联相比，可滑动交联增强了聚合物网络的流动性，并赋予材料低弹性模量。PDMS基体确保了所制备涂层的疏水性。这些特性协同作用，导致超低的冰粘附强度（13.0±1.3 kPa）和出色的机械耐久性。涂层上的冰粘附强度在20次结冰/除冰循环中保持在12 kPa，在800次磨损循环后逐渐增加到22 kPa。这种新颖的设计策略为针对特定应用的防冰/除冰解决方案向前迈进了一步。
