NOVELTY - Rollable flexible electric heating film comprises 45-70 wt.% thermoplastic elastomer, 6-40 wt.% graphene composite conductive agent, 1-5 wt.% antioxidant, 3-10 wt.% flow agent, 3-8 wt.% rubber plasticizer, and 1-3 wt.% Surfactant. USE - Rollable flexible electric heating film used as a heat source for all kinds of heating apparel. ADVANTAGE - The rollable flexible electric heating film has excellent flexibility. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing a rollable flexible electric heating film, which involves taking thermoplastic elastomer, carbon conductive agent, antioxidant, flow agent, rubber plasticizer and surfactant, mixing in the mixing equipment according to the ratio to obtain a mixed colloidal substance; placing the mixed gelatinous substance is on the training equipment; calendering the mixed gelatinous material after the training to obtain a curlable flexible electric heating film; and (2) a method for preparing a rollable flexible electrothermal membrane electrode, which involves cutting the rollable flexible electric heating film into a predetermined shape; printing two silver pastes on the cut flexible film; and pasting copper foil on the silver paste as a current collector the width of the copper foil is the same as the width of the silver paste.
