▎ 摘　　要

NOVELTY - Functional textile comprises a textile (110) having a certain size and certain thickness, and an electric planar heating element coating layer (120) (made of 15 wt.% polyvinylidene fluoride-based copolymer solution, which is a fixed polymer, 15-45 wt.% heating material, 15-45 wt.% graphene and carbon nanotube and 10-30 wt.% graphite nanofiber) coated on both sides of the textile surface. USE - Used as functional textile. ADVANTAGE - The functional textile: contains coating liquid composition having good electrical properties, resistance to oxidation, thermal conductivity, piezoelectricity, viscosity, adhesiveness, uniform exothermic durability and coating property; exhibits excellent flexibility, electrical conductivity and exothermic properties. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the structure of the functional textile. 110Textile 120Electric planar heating element coating layer
