▎ 摘　　要

NOVELTY - Preparing conductive material involves (a) dispersing graphene oxide in water to obtain a graphene oxide water solution, (b) immersing dried polyurethane foam in the graphene water solution and vacuum drying to obtain graphene oxide/polyurethalane foam, (c) immershing the graphene oxide or polyurethalene foam in a mixed solution of hydriodic acid and glacial acetic acid, taking out the polyure thane foam and washing with water and drying, (d) dispersing conductive reinforcement filler in the water, to obtain a conductive reinforcing filler water solution, and (e) immering the reduced graphene oxide / polyuretane foam into the conductive reinforced filler water liquid, and then taking out to obtain the conductivity material. USE - Method for preparing conductive material used in a conductive sealing strip, where conductive material is directly combined with the conductive glue to obtain a conductive sealing strip (claimed). ADVANTAGE - The conductive material has excellent performance of polyurethane foam, and also has good conductive performance and electromagnetic shielding efficiency. The conductive material is simple to prepare, cost-effective and suitable for large-scale popularization and application.
