Delamination, colloidal dispersion and reassembly of alkylamine intercalated graphite oxide in alcohols

Alkylamine intercalated graphite oxide delaminates to give colloidal dispersion in alcohols. Colloidal dispersion of the alkylamine intercalated GO increases with increase in chain length of the alcohols. The colloidal dispersions comprise of independent layers. The layers from these colloidal dispersions could be reassembled by evaporation or coagulation using acetone to form the parent layered solid. Layers from colloidal dispersions of two different alkylamine intercalated GO could be coassembled to get a solid in which the two different layers were stacked randomly. GO-bentonite composite could be obtained by a coassembly of layers from the colloidal dispersions of GO-amine and cetyl trimethyl ammonium intercalated bentonite.
