摘要

In this study, we report the first example of producing colloidally stable aqueous dispersion of Ni nanowires (Ni NWs) using graphene oxide (GO) as a surfactant. We subsequently used the produced Ni NWs/GO aqueous dispersion to prepare polymer nanocomposite dispersions where the polymer was synthesised using soap-free emulsion polymerisation. The produced polymer/Ni NWs/GO dispersion was designed to form a coating at ambient temperature when spray coated on a substrate. The obtained coatings can be thermally annealed to render them electrically conducting. This study showcased that emulsion-based approaches can be employed to prepare multi-filler nanocomposite coatings.
