Abstract

Mixing graphene oxide (GO) aqueous solution with tridodecylmethylammonium chloride (TDMAC) aqueous solution has gradually produced a precipitate of a complex of GO and TDMAC. The complex is soluble in many polar and nonpolar organic solvents, including low dielectric nonpolar organic solvents such as toluene and hexane. In addition, thin films cast the complex specified organic solutions under high humidity conditions have honeycomb-like structures with ordered self-organized macropores. Such insulating honeycomb films have become well conductive, when they were treated by the p-toluenesulfonicacid and then reduced by chemicals such as hydrazine or HI acid.
