Study on Composited Self-Lubricating Anti-Icing Coating with High Durability and Low Ice Adhesion: Key Role of B–O Dynamic Bonds
Source abstract
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.
