▎ 摘  要

NOVELTY - High conductive fabric based on graphene conductive paste comprises a flexible substrate, and a graphene film layer formed by uniformly coating graphene conductive paste on the surface of the flexible substrate. The graphene conductive paste is prepared by mixing graphene solution and water-soluble polyurethane solution according to a certain proportion. The graphene conductive slurry is a solution of graphene/polyurethane effective content ratio of 1-6%. USE - High conductive fabric based on graphene conductive paste for use in flexible sensors. ADVANTAGE - The fabric has high sensitivity and repeatable stability, simple preparation technique and low cost, and is suitable for industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method coating highly conductive fabric based on graphene conductive paste, which involves utilizing pressure atomization method to coat a water-soluble polyurethane solution with a concentration of 9-11 mass% on the surface of the flexible substrate to obtain a preliminary treatment substrate, utilizing the pressure atomization method to spray the graphene conductive slurry on the surface of the primary substrate prepared for 10-15 times, during the atomization spraying, it needs to be dried before spraying the next layer of graphene conductive, completely spraying slurry layer and drying to obtain a highly conductive substrate, utilizing pressure atomization again, coating water-soluble polyurethane on the surface of the highly conductive substrate, drying highly conductive substrate, to obtain highly conductive flexible sensor.
