NOVELTY - Coating fabric with electric heating element coating solution composed of high-tech composite with graphene/CNT blending technology comprises agitating 15 wt.% polyvinylidene fluoride (PVDF)-based copolymer solution, 15-45 wt.% graphene, and 15-45 wt.% CNT (carbon nanotube) by magnetic stirrer, preparing electric heating element coating solution, preparing fabric of certain size, coating electric heating element coating solution as a conductive ink by a knife edge method to coat the fabric with a circuit pattern of a specific shape, drying at room temperature for 24-48 hours, and forming planar heating element of the electric heating textile with a coating thickness of 0.1 mm plus minus 0.02 mm through high-temperature and high-pressure thermocompression process. USE - The method is useful for coating fabric with electric heating element coating solution composed of high-tech composite with graphene/CNT blending technology. ADVANTAGE - The method: improves electrical properties, resistance to oxidation, thermal conductivity, piezoelectricity, viscosity, durability, adhesion, and heat resistance; maintains body temperature in a low-temperature environment.
