▎ 摘　　要

NOVELTY - Functional textile (110) comprises a planar heating element coating liquid composition comprising 15-45 wt.% polyvinyl chloride-based copolymer solution as a fixed polymer, 15-35 wt.% graphene and 15- 45 wt.% carbon nanotubes (CNT) as a heating material, coated on one or both sides of the textile, and a coating layer. The textile is prepared by mixing polyester, polyurethane and nylon. The coating solution composition comprises a high-tech composite that is applied with graphene/CNT blending technology. USE - The functional textile is useful for producing textiles. ADVANTAGE - The functional textile has excellent electrical properties, resistance to oxidation, thermal conductivity, piezoelectricity, viscosity, adhesion, uniform heat resistance and coating properties, and exhibits excellent flexibility and electrical conductivity. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the functional textile. Functional textile (110) Electric planar heating element coating layer (120)
