▎ 摘　　要

NOVELTY - The method involves dispersing graphite alkene powder in organic solvent to obtain graphene oxide solution. Concentration of the graphene oxide solution is about 0.05mg/ml to 0.5mg/ml. A micro-pore filter film is covered on a graphene heating thin film to perform natural drying/heating operation. Stable uniformity of the graphene heating thin film is obtained by performing organic solvent soaking operation. A graphene thin film electrode is applied with certain voltage to produce heat. Surface density of the graphene heating thin film is about 10g/m2 to 50g/m2. USE - Graphene heating film preparing method. ADVANTAGE - The method enables effectively preparing a graphene heating film in a simple and easy manner without polluting environment. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of a graphene heating film.
