Description

technical field [0001] The invention relates to the technical field of electric heating materials, in particular to a graphene heating fabric and a preparation method thereof. Background technique [0002] With the development of society and the advancement of science and technology, people's requirements for heating are also increasing. Among them, graphene, as a good conductor of electricity and heat, can be used in the heating film to play a conductive role, combined with other components such as resin to form a resistance part, and then the graphene electric heating film can generate heat after electrification. For heating or heating. [0003] At present, most of the existing graphene electric heating films are based on PVC films, that is, a graphene-coated heating wire is applied between two layers of PVC films and a conductive copper foil is applied. However, due to the insufficient flexibility of PVC film in any direction, and the disadvantages of flammability and p...
