A method of preparing a fire extinguishing core-shell microcapsule by a one-pot oil-in-oil/ water emulsion technique. The method includes dissolving a fluid fluoroketone or hydrofluorocarbon fire extinguishing core material and a polymer shell material into a volatile solvent to form a composite mixture. The composite solution is emulsified into a polar phase and a non-polar phase by adjusting a concentration of a surfactant or via mechanical agitation to provide interfacial tension tuning. The volatile solvent is evaporated to precipitate a microcapsule having a fire extinguishing material core and a polymer shell. In a further aspect, the method includes incorporating the core-shell microcapsules in a polymer matrix.

Nanocomposite anticorrosion coating can be achieved by depositing alternating, multilayers of a cross-linkable polymer and dispersed and aligned inorganic platelets followed by cross-linking of the cross-linkable polymer. The cross-linkable polymer can be an externally cross-linkable polymer that is cross-linked by diffusing a cross-linking agent into the deposited multilayer coating. Alternately, the cross-linkable polymer can be a functionalized cross-linkable polymer that is cross-linked by self-curing, thermal heat curing, or light (e.g., UV) following deposition of the multilayer coating.
