We are developing aluminum nanoparticle (Al NP) passivation strategies based on our established protocols for polymerization of epoxide molecules with a view to fabricating air-stable Al NPs with long shelf-lives. Additionally we have discovered that our approaches have fortuitously yielded nanostructures with unprecedentedly high active Al contents (typically >80%). The incorporation of monomer substrates with carbon-carbon double and triple bonds has also afforded surprisingly stable materials. The resulting nanomaterials could fulfill requirements in fuels technology for the production and use of additives with high energy content and improved combustion rates even after several months of storage under ambient atmospheric conditions.
