Abstract

Icing phenomena have caused problems in aviation, electric power, and transportation. Lubricating coatings show anti-icing potential but are limited by ice adhesion and durability. Here, we constructed a durable, low-adhesion matrix/lubricant (SBU/SO) anti-icing coating by introducing a B–O-bonded silicone resin. The SBU/SO coating not only had high hardness but also displayed long-term low ice adhesion strength (4.06 kPa). It was found that the exchange of B–O bonds enhanced chain slipperiness and accelerated the movement of the lubricant, which disrupted the formation of ice nucleation and weakened the interfacial force between ice and the SBU/SO coating. Consequently, the incorporation of B–O dynamic bonds significantly enhanced the impact resistance of the SBU/SO coating because the sacrificial bond effect of the B–O dynamic bond effectively protected the lubricant and inhibited its loss from the matrix resin. This work inspired the design of a durable anti-icing coating with low ice adhesion, promoting practical engineering applications.

高耐久低冰粘复合自润滑防冰涂料研究：B-O动态键的关键作用

结冰现象给航空、电力和交通带来了问题。润滑涂层具有防冰的潜力，但受限于冰的粘附性和耐久性。在这里，我们通过引入b - o键合的有机硅树脂，构建了一种耐用、低粘附的基质/润滑剂（SBU/SO）防冰涂层。SBU/SO涂层不仅具有较高的硬度，而且具有长期较低的粘冰强度（4.06 kPa）。研究发现，B-O键的交换增强了链的滑溜性，加速了润滑剂的运动，破坏了冰核的形成，减弱了冰与SBU/SO涂层之间的界面作用力。因此，B-O动态键的加入显著提高了SBU/SO涂层的抗冲击性，因为B-O动态键的牺牲键效应有效地保护了润滑剂并抑制了其从基体树脂中的损失。这项工作启发了一种低冰附着的耐用防冰涂层的设计，促进了实际的工程应用。
