A mechanically durable induction heating coating with desirable anti-/de-icing performance

ABSTRACTABSTRACTThe anti-/de-icing technology based on induction heating offers significant advantages regarding fast heating, high efficiency, safety and environmental protection. However, the reported methods require the modification of base materials, which lacks universal applicability. Here, a universal and facile anti-/de-icing method is proposed based on induction heating. The durable induction heating coating was prepared by one-step spin coating with micron-sized nickel powder, epoxy resin and silicone resin. The induction heating ability of this coating was investigated by adjusting the proportion of composition, particle size and thickness. An optimal induction heating ability was achieved with the mass ratio of nickel powder and resin, particle size of nickel powder and coating thickness being 1.5, 7 μm and 1070 μm, respectively. We further show this coating can be applied for anti-/de-icing, demonstrated by its excellent de-/anti-icing performances. Finally, the mechanical durability of the coating was verified by the tape peel and sandpaper friction.KEYWORDS: Anti-/de-icinginduction heatingcoatingdurabilitynickel powderepoxy resinsilicone resinspin coating Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by National Key R&D Program of China: [Grant Number 2022YFB4602401]; National Natural Science Foundation of China: [Grant Number 52075071]; Opening Project of the Key Laboratory of Bionic Engineering (Ministry of Education), Jilin University: [Grant Number KF20200002]; Key Laboratory of Icing and Anti/De-icing of CARDC: [Grant Number IADL 20210405].
