Abstract
Nanotechnology involves scale, function, and composition that enable macroscopic properties with improved performance and high-value adding for any industry including the coatings industry. 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 nanomaterials to advanced manufacturing and commercial applications 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 and anti-microbial properties. We describe the preparation of very stable dispersions that can be used for coatings as well as anti-corrosion-superhydrophobic coatings. Interestingly, by preparation of nanoparticles that can be stabilized at dispersions, functional coatings can be prepared which have interesting uses in mitigating corrosion and killing bacteria. 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. An important consideration is their use as anti-corrosion additives and the importance of nanostructuring.
