▎ 摘　　要

NOVELTY - Graphene oxide sealing protection method of iron cultural relic comprises using modified graphene oxide/acrylic resin coating B72 composite coating for sealing, where the modified graphene oxide is acrylate graft modified graphene oxide nano sheet. USE - The method is useful for graphene oxide sealing protection of iron cultural relic. ADVANTAGE - The method is transparent and easy to be removed by organic solvent, and meets the reprocessing principle of cultural relic, does not affect the original appearance of the cultural relic, modified graphene oxide labyrinth barrier effect effectively blocking oxygen, moisture and other corrosion factors.
