Graphene heating film and preparation method thereof

一种石墨烯发热膜及其制备方法

Abstract

The invention provides a graphene heating film and a preparation method thereof. The graphene heating film is characterized by comprising a first insulated waterproof layer, an electrode layer, a heating film layer and a second insulated waterproof layer, wherein the first insulated waterproof layer, the electrode layer, the heating film layer and the second insulated waterproof layer are pasted into an integral structure; and the heating film layer is a graphene film. The preparation method of the graphene heating film comprises the following steps: (1) fabricating the graphene film; (2) covering the second insulated waterproof layer with a bonding adhesive; (3) bonding the second insulated waterproof layer and the graphene film into a whole; (4) removing a metal substrate on the graphene film; (5) pasting the electrode layer on the graphene film; (6) pasting the first insulated waterproof layer on the electrode layer; and (7) connecting the electrode layer and a lead wire. According to the graphene heating film and the preparation method thereof provided by the invention, the heating efficiency is high; large-area transferring of the graphene film can be achieved; the transfer time is short; and the transfer rate is high.
