▎ 摘　　要

NOVELTY - Preparation of high tensile strength graphene-diazo resin crosslinked composite material involves adding graphene oxide to deionized water, performing ultrasonication to obtain uniform dispersion of graphite oxide, adding 0.1-2 mL diazo resin at room temperature in dark room, stirring for 2-12 hours, performing vacuum filtering using anodized aluminum filter film, drying, peeling off composite film from membrane, performing UV light irradiation for 120-300 seconds, placing in hydrogen iodide solution at 100 degrees C for 1-2 hours, cooling and drying. USE - Method for preparing high tensile strength graphene-diazo resin crosslinked composite material (claimed). ADVANTAGE - The method is simple and easy to operate. The crosslinked composite material has excellent mechanical property and conductivity.
