▎ 摘　　要

NOVELTY - The film has a graphene oxide film layer (1), a supporting layer (2), an outer cover layer (3), a connecting wire and a mattress (5) connected with each other, where the graphene oxide layer is a continuous n-shaped bent strip shape. An end of the graphene oxide layer is located on a left upper corner of an electrical heating film. Another end of the graphene oxide layer is positioned at a right lower corner of the electrical heating film. The supporting layer includes an upper supporting layer and a lower supporting layer. The outer cover comprises an upper outer cover sheet and the lower outer cover sheets. An edge of a left upper hole (51) is provided with two plastic buckling pieces for fixing the electric heating film. An upper end line passes through the left lower hole and passes through from the lower end. An edge of the lower hole is equipped with two plastic buckle pieces to fix the electrical heat film. The lower end line penetrates through a right lower hole (52). USE - Graphene electrothermal film for use in civil device field and pipeline anti-freezing, building heating system for replacing current of wall underfloor heating product. ADVANTAGE - The film is good in heating effect, quick in heating and capable of quickly and effectively heating. The graphene film is not only firm and durable, but also not easy to be oxidized and can be used for many years. The proper fixing mode of the upper groove, the lower groove and the outer cover, and the wire leading-out mode of mattress provided with the holes, both enable the risk of damage in use to be reduced to the minimum. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene electro-thermal film assembling method for implementing the graphene electric heating film. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a graphene electrothermal film. 1Graphene oxide film layer 2Supporting layer 3Outer cover layer 5Mattress 51Left upper hole 52Right lower hole
