Non-mobility graphene oxide grafted anti-aging agent and preparation method thereof

The invention provides a non-mobility graphene oxide grafted anti-aging agent and preparation method thereof. 4-aminodiphenylamine is used for carrying out grafting modification on graphene oxide by so as to enable a hydroxyl group in the carboxyl group of graphene oxide to be replaced with an R group, wherein the structural formula of the R group is described in the description; the grafting rateof the R group is 7-15wt%. The preparation method comprises the following steps: (1) dissolving graphene oxide into thionyl chloride, carrying out a refluxing reaction, separating out a reaction product, and washing to remove thionyl chloride so as to obtain thionyl chloride modified graphene oxide; (2) adding the thionyl chloride modified graphene oxide into dimethylformamide, carrying out ultrasonic treatment to enable the thionyl chloride modified graphene oxide to be fully dissolved, and dissolving 4-aminodiphenylamine into dimethylformamide; then, mixing the thionyl chloride modified graphene oxide solution with
