▎ 摘  要

NOVELTY - Preparing a graphene/bacterial cellulose composite material, where bacterial cellulose and graphene are co-cultured in situ, comprises: (a) preparing a bacterial cellulose culture fluid, and sterilizing at high temperature under high pressure for 30-60 minutes; (b) inoculating the strain in the bacterial cellulose culture fluid; (c) carrying out ultrasonic treatment on graphene dispersion liquid; (d) rocking the mixed liquid; (e) putting the liquid in a 28 degrees C thermostatic oven; and (f) cleaning the graphene/bacterial cellulose composite material, and carrying out freeze-drying. USE - The method is useful for preparing graphene/bacterial cellulose composite material (claimed). ADVANTAGE - In the composite material, the graphene is evenly distributed on the bacterial cellulose fibers, thus effectively inhibiting the defect of high agglomeration tendency of graphene particles. DETAILED DESCRIPTION - Preparing a graphene/bacterial cellulose composite material, where bacterial cellulose and graphene are co-cultured in situ, comprises: (a) preparing a bacterial cellulose culture fluid, and sterilizing at high temperature under high pressure for 30-60 minutes; (b) inoculating the strain in the bacterial cellulose culture fluid, and rocking in a rocker for 12-48 hours; (c) carrying out ultrasonic treatment on 0.2mg/ml graphene dispersion liquid for 1-3 hours, and adding the graphene dispersion liquid into the bacterial cellulose culture fluid with the strain, where the volume ratio of the graphene dispersion liquid to the bacterial cellulose culture fluid is 1:5-1:10; (d) rocking the mixed liquid in the rocker for 12-24 hours; (e) putting the liquid in a 28 degrees C thermostatic oven, and standing for 1-2 weeks to obtain the graphene/bacterial cellulose composite material; and (f) cleaning the graphene/bacterial cellulose composite material, and carrying out freeze-drying.
