In order to solve the problem of UAV composite surface icing， an integrated structure of superhydrophobic coating， electrothermal film and composite surface is designed and prepared. The multilayer integrated structure consists of the superhydrophobic coating preparation method and the embedded electrothermal film process. The superhydrophobic coating based on epoxy resin has excellent hydrophobicity， which increases 18 times longer than untreated one for delayed icing time of water droplets， and thus the anti-icing effect is improved. The integrated structure of heating film and composite surface enhances the directivity of heat conduction， which improves the efficiency of electrothermal conversion， and thus the de-icing effect also is improved. The de-icing and anti-icing tests of integrated structure are verified by self-designed test platforms. The experimental results show that the energy consumption is cut by about 35% by integrated structure of superhydrophobic coating， electrothermal film and composite surface. The integrated structure is feasible to achieve the anti/de-icing effect and reduce energy consumption.
