▎ 摘 要
NOVELTY - Bacterial cellulose/graphene/iron oxide composite film, prepared by curing bacterial cellulose/graphene oxide/iron oxide nano-fiber electrostatic self-assembly, carrying out reduction and carbonization, then uniformly dispersing iron oxide and graphene oxide in the bacterial cellulose nano-fiber matrix, is claimed. USE - The composite film is useful in lithium-ion battery anode material, super capacitor, tissue engineering and biosensor coating material. ADVANTAGE - The composite film has accurately adjustable thickness, mechanical strength and good biocompatibility.
