NOVELTY - Preparing graphene oxide reinforced polymethyl methacrylate/carbon microsphere composite material involves carrying out a hydrothermal reaction using glucose solution as a carbon source, and after the reaction, washing the product various times, then filtering and drying to obtain carbon microspheres. The dried carbon microspheres are dissolved in a mixed solution of deionized water and absolute ethanol, and added a mixed solution of silane coupling agent and absolute ethanol. The reaction is carried out under condensing reflux heating conditions, the product is washed various times after the reaction, and then filtered and dried to obtain modified carbon microspheres. A solution of the dried modified carbon microspheres, water and methyl methacrylate are prepared, recorded as solution A, poured in nitrogen and continue stirred until the mixture is uniform. A graphene oxide aqueous solution is prepared, recorded as solution B, continue to stirred until the mixture is uniform. USE - Method for preparing graphene oxide reinforced polymethyl methacrylate/carbon microsphere composite material. ADVANTAGE - The method enables to prepared graphene oxide reinforced polymethyl methacrylate/carbon microsphere composite material. DETAILED DESCRIPTION - Preparing graphene oxide reinforced polymethyl methacrylate/carbon microsphere composite material involves carrying out a hydrothermal reaction using glucose solution as a carbon source, and after the reaction, washing the product various times, then filtering and drying to obtain carbon microspheres. The dried carbon microspheres are dissolved in a mixed solution of deionized water and absolute ethanol, and added a mixed solution of silane coupling agent and absolute ethanol. The reaction is carried out under condensing reflux heating conditions, the product is washed various times after the reaction, and then filtered and dried to obtain modified carbon microspheres. A solution of the dried modified carbon microspheres, water and methyl methacrylate are prepared, recorded as solution A, poured in nitrogen and continue stirred until the mixture is uniform. A graphene oxide aqueous solution is prepared, recorded as solution B, continue to stirred until the mixture is uniform. The uniformly stirred solution B is stirred to the uniformly stirred solution A to obtain solution C, and continue to stir until the mixture is uniform. The sodium dodecylbenzene sulfonate is added to the above-mentioned uniformly stirred and mixed solution C and heated to react, and continue to blow in nitrogen and stirred during the whole process, and after the reaction is over, the product is filtered, centrifuged, washed and dried to obtain the graphene oxide reinforced polymethyl methacrylate/carbon microsphere composite material.
