NOVELTY - The utility model claims a graphene gradient heating film, comprising a substrate, a graphene conductive layer and gradient electrode layer, and the electrode layer of the gradient is provided on at least one side of the graphene conductive layer. the distance between positive negative electrode and the gradient electrode layer of step-shaped increasing from one end to the other end/reduced, or firstly is stepped increase and then is stepped to reduce, or firstly is stepped to first decrease and then increase is stepped, so that in the same heating area, realizing the different position gradient heating. graphene gradient heating film of this utility model can better market product demand.
