Colloidal graphene oxide/polyaniline film forming nanostructure by controlled acidity

Processability is an essential requirement in application of polyaniline/graphene composite. While solution and melt processing are not viable options, we have shown that using aqueous colloidal stable dispersion results in bio-friendly easy film forming product. Polyaniline chains were grafted to graphene oxide (GO) simultaneously reducing it to graphene. Structural evolution as a function of aniline/GO ratio was studied by Scanning electron microscope (SEM) images, and reported. Effect of acidity and initial monomer concentration on colloidal stability is discussed.
