Abstract
Disclosed are a chitin/graphene composite sponge and a preparation method and a use thereof. The method comprises mixing and ball-milling a certain amount of flake graphite and chitin, dissolving a mixture of the flake graphite and the chitin in a NaOH/urea solvent, performing centrifugal separation, dispersing evenly, cross-linking with an epichlorohydrin cross-linking agent, standing, dialyzing, and freeze-drying, thus obtaining the chitin/graphene composite sponge.
Claims17
A preparation method of a chitin/graphene composite sponge, wherein the method comprises mixing and ball-milling a flake graphite and a chitin to obtain a chitin/graphene composite material first;
- and evenly dispersing the chitin/graphene composite material in a solvent, removing unexfoliated graphite through centrifugation, cross-linking with an epichlorohydrin, dialyzing, and freeze-drying, thus obtaining the chitin/graphene composite sponge.
