▎ 摘　　要

NOVELTY - Preparing a self-repairing graphene/thermoplastic resin coating involves mixing a thermoplastic resin solution with graphene, mixing at high speed for 1-3 hours, uniformly removing air bubbles in the mixed solution, and applying the obtained mixed solution to the substrate to obtain self-repairing graphite. The olefin/thermoplastic resin coating layer has a ratio of the graphene to the thermoplastic resin of 0.05-0.1% by weight. USE - Method for preparing a self-repairing graphene/thermoplastic resin coating. ADVANTAGE - The method enables to prepare a self-repairing graphene/thermoplastic resin coating, which has low energy consumption, low cost, simple repair process, economical, and easy to realize industrialization.
