DETAILED DESCRIPTION - Processing graphene-based anticorrosive coating using 20 pts. wt. epoxy resin, 6 pts. wt. modified graphene oxide, 40 pts. wt. solvent, 10 pts. wt. self-repairing microcapsules, and 3 pts. wt. additives as raw material. The modified graphene oxide is prepared by modifying graphene oxide with a modifier, where the graphene oxide is prepared by oxidizing graphene. The raw material components of the modifier are 10 pts. wt. sodium borohydride, 40 pts. wt. tetrahydrofuran, 3 pts. wt. iodine, and 15 pts. wt. dilute hydrochloric acid. The raw material components of the self-healing microcapsules are 2 pts. wt. alkylbenzene sulfonate, 3 pts. wt. phosphoric acid, 20 pts. wt. phenolic resin, and 30 pts. wt. tetraethylorthosilicate. The raw material components of the additives are 5 pts. wt. polyaniline, 3 pts. wt. aluminum sulfate, 2 pts. wt. pyridine, and 5 pts. wt. copper oxide. The solvent includes toluene and n-butanol in a mass ratio of 1:1. The sodium borohydride, tetrahydrofuran, iodine, dilute hydrochloric acid, alkylbenzene sulfonate, phosphoric acid, phenolic resin, tetraethylorthosilicate, epoxy resin, polyaniline, aluminum sulfate, pyridine and copper oxide are weighed. The prepared graphene is oxidized with a strong oxidizing agent to obtain graphene oxide. The prepared graphene oxide is placed in a beaker, dissolved in tetrahydrofuran with sodium borohydride, and then slowly dropped the mixed liquid of tetrahydrofuran and iodine to obtain modified graphene oxide. The prepared alkylbenzene sulfonate is placed place in a beaker with phosphoric acid and phenolic resin under heating and stirring for 30 minutes to obtain material A. The prepared tetraethyl orthosilicate is placed in a hydrochloric acid solution under heating and stirring in a water bath to obtain material B. The prepared material A and material B are mixed with hydrochloric acid to obtain self-healing microcapsules. The prepared polyaniline is placed in a beaker with solvent under stirring for 15 minutes, and then placed in an ultrasonic machine for ultrasonic dispersion for 2 hours to obtain material C. The prepared epoxy resin is mixed with the solvent and the material C and modified graphene oxide under stirring for 20 minutes to prepare self-healing microcapsules. The prepared self-healing microcapsules, the aluminum sulfate, copper oxide, and pyridine are stirred for 40 minutes, and then placed in an oven and vacuumed for 15 minutes to obtain the anticorrosive coating.
