A scalable, synthesis process has been used to create nanostructures in polymer matrices to form polymer matrix nanocomposites (PMNCs) with specific photochemical functionalities. Various metal and metal oxide nanoparticles exhibiting catalytic, photocatalytic and photochromic behaviors have been produced directly in polymers using a modified vapor deposition method. Under different processing conditions, the resulting composites display various optical absorption characteristics. We investigate the effects of different thermal processing parameters, such as processing temperatures and dwell times (for vaporization and decomposition of precursors), on nanoparticle size and distribution. We also incorporate laser irradiation as localized heating sources for the polymer matrix in the synthesis process to actively control the precursor diffusional pathways. Spatially adjusting the precursor concentrations in the matrix allows for control of nanoparticle formation and results in a patterned nanocomposite. These results demonstrate the possibility of synthesizing nanocomposites with specific nanoparticle location, size, and distribution in a polymer matrix and outline processes that can be used to pattern materials with tailored photochemical properties.
