Abstract

The invention discloses a graphene heating film and a preparation method thereof. The graphene heating film is obtained by coating graphene slurry on a base material; the graphene slurry is prepared from 10 to 20 parts of graphene oxide powder, 5 to 8 parts of nanometer bamboo charcoal powder, 30 to 50 parts of water and 3 to 5 parts of bonding agents. The graphene heating film is obtained by compounding the graphene oxide powder and the nanometer bamboo charcoal powder; the heating function is realized; the effects of regulating the humidity and purifying the air are also achieved; the graphene heating film is also very suitable for being used as a heating element of an electric heater. Compared with the prior art of firstly preparing the graphene film and then transferring the graphene film onto a target substrate, the preparation process of the graphene slurry has the advantages that the preparation process is simple; the graphene slurry is directly coated onto the target substrate;the transferring process is omitted; the crushing of the film in the transferring process is avoided; the process is stable; the production efficiency is high.
