Abstract
This invention provides a graphene-based peelable composite material for cultural relic preservation and its preparation method. The composite material is composed of graphene oxide, CsPbX3 type perovskite compound, silica sol, aqueous film-forming agent, deionized water, and additives in a specific ratio. The preparation method includes steps such as dispersion, composite grinding, and mixing. The coating formed by this composite material exhibits excellent weather resistance and can be gently and completely peeled off without damage by increasing the ambient humidity to 75%-85%, achieving a balance between long-term and reversible preservation of cultural relics, while being safe and environmentally friendly.
