▎ 摘　　要

NOVELTY - A full heat-exchange graphene paper film is prepared from raw material including plant fiber slurry, high-molecular polymer, flame retardant, antibacterial agent and graphene aqueous slurry. The plant fiber slurry is imported softwood slurry or a mixed slurry of imported softwood slurry and hardwood slurry. The graphene aqueous slurry has active component content of 5-15%, and viscosity of 1000-6000 mPa.second. The graphene paper film has air permeability of 0.2 mu m/Pa.second or less, and moisture permeability of 1000 g/m2.24 hours or more. USE - Full heat-exchange graphene paper film.
