摘要

This study aims to develop a superhydrophobic laser-induced graphene (LIG)-based composite coating with enhanced electrothermal and anti-icing properties. To address the inherent limitations of pristine LIG, fluorinated ethylene propylene (FEP) nanoparticles were uniformly dispersed in an electronic fluoride solution, spray-coated onto LIG, and annealed to form a three-dimensional micro-/nanostructured architecture. The resulting composite exhibited a water contact angle of 150.1° and extended the freezing delay time from 75 s for pristine LIG to 343 s, representing more than a fourfold improvement. Moreover, the electrothermal de-icing performance was significantly enhanced: under identical voltage conditions, the heating response time was reduced by a factor of 2 to 6, while the maximum achievable temperature increased by 1.5 to 2 times. Notably, the composite achieved rapid de-icing within a very short period and readily surpassed the temperature limits of pristine LIG. The coating maintained stable hydrophobicity after repeated de-icing cycles. This approach integrates superhydrophobicity, anti-icing capability, and thermal stability, offering a promising strategy for the design of LIG-based composites and providing valuable insights for applications in the aviation, automotive, and construction industries.
