NOVELTY - Preparing honeycomb-shaped ordered porous graphene coating comprises e.g. (i) taking concentrated sulfuric acid, expanded graphite, adding sodium nitrate into a round bottom flask and stirring in a ice water bath, adding potassium permanganate into the round bottom flask for six times in one hour, and continuously stirring, replacing the ice bath with an oil bath, heating, and reacting, (ii) polishing the titanium sheet, ultrasonically cleaning with deionized water, and blowing the nitrogen, and drying, and (iii) combining the phase transfer with Breath-Figure self-assembly method. USE - The method is useful for preparing honeycomb-shaped ordered porous graphene coating. ADVANTAGE - The method: provides antibacterial properties; regulates the function of osteoblasts; and promotes the rapid bone integration of osteophyte titanium material. DETAILED DESCRIPTION - Preparing honeycomb-shaped ordered porous graphene coating comprises (i) taking 46 ml 98% concentrated sulfuric acid, 2 g expanded graphite with 500 nm, adding 1 g sodium nitrate into a 250 ml round bottom flask and stirring in a ice water bath, adding 6 g potassium permanganate into the round bottom flask for six times in one hour, and continuously stirring for 2 hours, replacing the ice bath with an oil bath, heating at 35-40 degrees C, and maintaining reacting for 1.5 hours, processing oxidation slowly at this stage, when the viscosity of the system maintains rising, adding 100 ml deionized water into the system, and controlling the temperature of the system quickly to 98 degrees C, continuously stirring at this temperature for 2.5 hours, slowly adding hydrogen peroxide solution into the system, and until no bubbles are producing, (ii) polishing the titanium sheet into a deionized water, ethanol, and acetone, ultrasonically cleaning with deionized water for 10 minutes, and blowing the nitrogen, and drying, and (iii) using titanium surface porous graphene oxide (GO) coating, and combining the phase transfer with Breath-Figure self-assembly method, and transferring graphene oxide from aqueous phase into chloroform phase.
