  • Title: pH-Responsive chitosan-mediated graphene dispersions.
    Author: Fang M, Long J, Zhao W, Wang L, Chen G.
    Journal: Langmuir; 2010 Nov 16; 26(22):16771-4. PubMed ID: 20936800.
    Abstract:
    Homogeneous aqueous suspensions of graphene have been prepared by chemical reduction of graphene oxide in the presence of chitosan. The graphene sheets in thus prepared suspensions can be switched reversibly between a well dispersed and a more aggregated state with pH as a stimulus.
