Abstract
An attachable self-resistance heating/super-hydrophobic integrated gradient film material. The film material is made of an adhesive resin, an electrically and thermally insulative resin, a thermally and electrically conductive filler, and a thermally conductive insulating filler. The adhesive resin and the electrically and thermally insulative resin respectively form an adhesive layer and a base body, and the two are bonded together. The thermally and electrically conductive filler and the thermally conductive insulating filler are respectively added to an intermediate layer and an upper layer of the base body, to divide the base body into three gradient regions from top to bottom, wherein a super-hydrophobic structure is constructed on the surface of the uppermost area.
