The large interest in graphene-based materials and other carbon-based polymorphs and nanomaterials are truly far-reaching. The industrial scale and possibility of applying these to advanced manufacturing and commercial application have resulted in high throughput synthesis and lower costs. There is primary interest on their electrical and thermal conductivity properties. However, other applications are based on their ability to form very stable colloidal complexes. This talk will focus on the class of graphene (G) and graphene oxide (GO) nanomaterials that have been prepared with high loading in polymer matrices and ultrathin films to result in: anti-corrosion coatings, semiconductor thin films, patterning, and anti-microbial properties. We describe the preparation of very stable dispersions that can be used for nanopatterning in films as well as anti-corrosion-superhydrophobic coatings. Interestingly, by preparation of colloidal particles that can be stabilized at liquid-liquid and air-liquid interfaces, functional Janus type nanoparticles can be prepared which have interesting uses in dispersants, rheological modifiers, and smart fluids.
