▎ 摘　　要

NOVELTY - Use of breathable graphene film is claimed for detecting light intensity stability. The graphene sheet has an average size of more than 100 mu m in plane direction, and is composed of 1-4 layers of graphene sheets. USE - Breathable graphene film for detecting light intensity stability. ADVANTAGE - The breathable graphene film has good electromagnetic shielding performance, improved breathable stability, light intensity stability, thermal conductivity, rapid heating and expansion under light, shielding effectiveness, and high sensitivity detection of light. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphite oxide crystals before filtration.
