▎ 摘　　要

NOVELTY - Graphene mica double-layer paper comprises 1-15 wt.% of graphene, and 85-99 wt.% of mica, preferably, the graphene comprises graphite stripping, where the graphene prepared by redox method, the CVD method of the carbon-containing gas, and/or at least two of the graphene prepared by the pyrolysis method of the biomass resource. USE - The graphene mica double-layer paper is useful in electric heating device (claimed). ADVANTAGE - The graphene mica double-layer paper: has good heat resistance, non-flammable property, acid and alkali resistance, and has good radiating performance, improves the reliability and service life of the thermoelectric device operation. The method: has easily obtaining raw materials, simple preparation, and prepares graphene double-layer mica paper with radiating performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for mica electric heating plate or electric heating device comprising the graphene-mica paper.
