Fabrication of Graphene Superhydrophobic Coating with Excellent Superhydrophobic/Electrothermal Synergistically Anti-icing Fuction

This research reported an effective de-icing method by combining the superhydrophobic and electrothermal functions. Due to the high specific surface area, the modified graphene powder exhibited superhydrophobic property. The coating was achieved by further partially embedding the graphene powders onto the substrate. The partiall-embeded structure offers the composite excellent mechanical robustness, which could retain superhydrophobicity after 10.00 m abrasion (5 kPa pressure). Furthermore, the excellent conductivity of the graphene offered the composite excellent electrothermal property. Therefore, this superhydrophobic composite could melt ice layer (2 mm thickness) within ~121 s after applying 20 V voltage.
