Graphene composites have attracted extensive attention in various fields due to their excellent electrical conductivity and high thermal conductivity. In order to study the application of graphene heating film in electro-thermal de-icing, the temperature rise rate of graphene and resistance wire as heating elements was compared. The heating element is prepared into a heating film which can be used for electro-thermal de-icing. It was studied based on a self-built electro-thermal de-icing laboratory that the effects of different heat flux and freezing temperature on the de-icing effect of graphene heated films. The experimental results showed that the heating rate of the graphene heating element was faster than that of the resistance wire, and the heating film prepared from graphene as the heating element generated more uniform heating. With the increase of heat flux, the shorter the de-icing time, the better the effect. The lower the freezing temperature, the longer the de-icing time. It has been proved that graphene can be used as an ideal heating film material in the field of electro-thermal de-icing.
