▎ 摘  要

NOVELTY - The method involves dispersing (122) nano-graphene sheets with mechanical force to form graphene suspension solution. A boiling point of first solvent is not greater than 80 degrees C and second solvent is not less than 120 degrees C. A curable resin (121) is added to graphene suspension solution. The nano-graphene sheets and curable resin are dispersed with mechanical force to form a graphene resin solution. The graphene resin solution on hydrophobic protective layer (13) is coated or printed. The graphene resin solution is cured to form graphene conductive layer (12) adhered to hydrophobic protective layer. A hot glue layer (11) is coated on the graphene conductive laye. A fibrous tissue (10) is attached on the hot glue layer and the fibrous tissue is heated and pressed to allow the hot glue layer respectively adhere to the graphene conductive layer and the fibrous tissue, to form a graphene conductive fabric (1). The hydrophobic protective layer is selected from silicone and polyurethane resins. USE - Method for manufacturing graphene conductive fabric. ADVANTAGE - The manufacturing cost of the method for manufacturing graphene conductive fabric can be effectively reduced, so that the method has broad applicability in the industries. The graphene conductive layer can be prevented from filling the interstices of the fibrous tissue, so as to keep the conductivity, and the hydrophobic protective layer can protect the graphene conductive layer from exfoliation caused by washing. The fabrics including the graphene conductive layer can effectively increase design flexibility of the functional clothing, and significantly reduce the manufacturing cost. The sandwich-like structure can significantly improve the adhesion of the graphene conductive layer to the fibrous tissue, and maintain integrity of the graphene conductive network. The weight ratio of the nano-graphene sheets in the graphene conductive layer can be increased, and the volume resistance of the graphene conductive layer can be reduced to meet the conductivity required by the functional clothing. The graphene conductive fabric has a surface resistance and tensile property, so that can prevent conductive lines from breakage, meet the requirement of the conductive lines for physiological sensors and increase wearing comfort. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view schematically illustrating a graphene conductive fabric.
