Attachable self-resistance heating/super-hydrophobic integrated gradient film material

An attachable self-resistance heating/super-hydrophobic integrated gradient film material, wherein the film material is prepared from an adhesive resin, an electrically and thermally insulative resin, a thermally and electrically conductive filler (3) and a thermally conductive insulating filler (4), wherein:

• the adhesive resin and the electrically and thermally insulative resin form an adhesive layer (1) and a base body (2) bonded together, respectively, with the base body (2) on the adhesive layer (1);
• the thermally and electrically conductive filler (3) and the thermally conductive insulating filler (4) are added into an intermediate layer and an upper layer of the base body (2), respectively;
• the base body (2) is divided into three gradient regions from top to bottom:
• a thermally conductive insulating region (21), an electrically and thermally conductive region (22) and an electrically and thermally insulative region (23), wherein a super-hydrophobic structure is constructed on a surface of the thermally conductive insulating region (21),
• wherein the thermally conductive insulating filler (4) is selected from graphene oxide, aluminum nitride ceramic and boron nitride ceramic.
