We report on the polymerization of acrylic monomers on incipient aluminum nanoparticle cores and explore the effect of changing the monomer size and/or chain length on the resultant stability of the passivated particles. The synthesis protocol is based on the decomposition of molecular alane reagent using a titanium (IV) complex as a catalyst. The accessibility to the active aluminum core, with the different monomer sizes, is also evaluated and presented in this work using the hydrogen emission method. When varying the monomer chain lengths, the trend shows longer access time to the active metallic core with for long chained monomer caps. The ideal Gas Law is employed to determine the amount of active aluminum in the samples. We also present preliminary results from PXRD (powder X-ray diffraction), TEM (transmission electron microscopy), DSC/TGA (differential scanning calorimetry/thermal gravimetric analysis) and DLS (dynamic light scattering).
