▎ 摘　　要

NOVELTY - A graphene electrothermal material preparing method involves taking graphene slurry as a conductive filler and aqueous polyurethane emulsion as a binder, and adding 3 mass% emulsifier to prepare a graphene electrothermal carbon slurry, followed by taking polyethylene terephthalate as carrier, placing 2-20 wires on the polyethylene terephthalate film, maintaining the 0.1-50 cm distance between two adjacent wires, coating the graphene electrothermal carbon slurry on the polyethylene terephthalate film, and drying to obtain the finished product. USE - Method for preparing graphene electrothermal material. ADVANTAGE - The method enables preparing graphene electrothermal material with controllable electrothermal performance and multiple heating performance, in eco-friendly manner.
