NOVELTY - Oxidized graphene-bacterial cellulose composite material comprises bacterial cellulose and grapheme oxide composite. USE - As oxidized graphene-bacterial cellulose composite material used in biomedicine. ADVANTAGE - The graphene-bacterial cellulose composite has simple process, no toxic chemical agent, is safety, green and environment-friendly, has good composite, flexibility, and absorption properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing oxidized graphene-bacterial cellulose composite material involving 1) dispersing deionized water mass volume concentration is of 0.2-0.8 mg/ml graphene dispersion liquid, via ultrasonic for 2-3 hours, ultraviolet sterilizing for 3 times, each time for 15 minutes, step 2) a bacterial cellulose culture liquid, pH of the culture liquid is 4.5, and the sterilizing boiler at 120?OC, in 0.1 Mpa low for 30 minutes, step 3), the step 1) of the graphene oxide dispersion liquid obtain in step 2) to obtain of bacterial cellulose in culture liquid, where the volume ratio of the graphene oxide dispersion bacterial cellulose culture liquid is 1:10-20, using ultrasonic cell crushing ultrasonic crushing process, set the working each 3-5 seconds, 3 second is one times, 60-80 times is one group, dispersing the sheet-shaped particle uniform graphene oxide in the bacterial cellulose culture liquid in the step 4), step 3) obtain mix of liquid adding wood vinegar in a bacillus, inoculation of rear mix liquid at 150 revolution/minute at 20-30 degrees C, lower shaking co-culture 5-7 days, cellulose-producing bacteria of the graphene oxide sheet-shaped particle is coated on substrate in the cellulosic web fiber structure, the growth material is graphene oxide, bacterial cellulose composite material, using clean water.
