NOVELTY - Preparing graphene intercalation silver material by e.g.: placing ice in the beaker to form ice water bath; adding concentrated sulfuric acid into the beaker and placing the beaker into the electromagnetic stirrer to stir, adding graphite and sodium nitrate, placing in beaker, stirring, adding potassium permanganate, taking de-ionized water placing in beaker, heating; adding hydrogen peroxide into the beaker, filtering when it is hot and washing with hydrochloric acid and deionized water; drying washed solid to obtain graphene oxide; grinding and crushing the graphene oxide into the beaker; pouring water into the beaker; heating, stirring and performing ultrasonic treatment to obtain graphene oxide suspension; adding silver nitrate into the beaker filled with graphene oxide suspension, placing reducing agent, and placing the beaker in the atmosphere of inert gas, introducing ammonia gas; adding dispersant, and cleaning with deionized water, introducing ammonia gas and drying. USE - The method is useful for preparing graphene intercalation silver material. ADVANTAGE - The graphene oxide has good stabilizing effect to the nano-silver, so as to improve the antibacterial effect. The production process is simple, worth to be popularized in industrial preparation and laboratory experiment; avoids the agglomeration of nano-silver, and improves the production benefit of graphene intercalation silver material. DETAILED DESCRIPTION - Preparing graphene intercalation silver material, comprises: (S1) using Hummers method for preparing graphene oxide: preparing a beaker of 500 ml, placing ice in the beaker to form ice water bath; adding 46 ml concentrated sulfuric acid into the beaker and placing the beaker into the electromagnetic stirrer for fully stirring, then adding 2 g graphite and 1 g sodium nitrate, adding into beaker, stirring for 5 minutes, adding 6 g potassium permanganate for stirring, taking de-ionized water, taking beaker, heating; adding 10 g hydrogen peroxide into the beaker, filtering when it is hot and washing with hydrochloric acid and deionized water; placing the washed solid into a drying box for drying to obtain graphene oxide; (S2) preparing graphene oxide suspension: grinding and crushing the graphene oxide into the prepared beaker; then pouring water into the beaker; heating, stirring and placing into ultrasonic device for ultrasonic treatment to obtain graphene oxide suspension; and (S3) preparing graphene intercalation silver material: taking 30 g silver nitrate into the beaker filled with graphene oxide suspension, stirring, placing reducing agent in the stirring process, and placing the beaker in the atmosphere of inert gas, introducing ammonia gas to purge; stirring for 5 minutes, adding dispersant, and cleaning with deionized water, continuously introducing ammonia gas to dry, placing into a drying box at 60degrees Celsiusto dry.
