PREPARATION METHOD FOR REDUCED GRAPHENE OXIDE/ASPERGILLUS NIGER CELLULOSE AEROGEL

摘要

Provided is a preparation method for a reduced graphene oxide/Aspergillus niger cellulose aerogel, comprising (1), mixing a graphene oxide dispersion, Aspergillus niger and a culture medium solution, and co-culturing same under conditions suitable for Aspergillus niger reproduction so as to form a ball of Aspergillus niger coated with the graphene oxide dispersion; (2), washing the ball cultured in step (1) with deionized water until clean and freeze-drying and shaping same by utilizing a freeze-drying technology so as to form a graphene oxide/Aspergillus niger cellulose aerogel; and (3), subjecting the graphene oxide/Aspergillus niger cellulose aerogel prepared in step (2) to carbonization treatment so as to obtain the reduced graphene oxide/Aspergillus niger cellulose aerogel having hydrophobicity. The hypha obtained by the method has a stable structure, has a good hydrophobicity and lipophilicity, and can be used as an adsorbing material.
