Abstract:

Synthesis of Robust Nanoporous All-Polymer Aerogels as Multifunctional Materials Demonstrated extremely strong aerogels with polyureas, polyimides, polyamides KevlarTM-like, polybenzoxazines, polyacrylonitrile-co-diacrylate, as well as polynorbornene and polydicyclopentadiene. Development and Self-Assembly of Multifunctional Inorganic-Polymer Hybrid Materials for Solar Energy Applications Demonstrated convenient synthesis of various semiconducting nanoparticles, studied functionalized polyoxometalates POMs, and developed novel conjugated systems with foldamers and dendrimers. Processing and Mechanical Characterization of Polyurea Aerogels Polyurea PUA aerogels were proven to be mechanically strong, especially in terms of strength to weight. PUA aerogels can take extreme loads under compression. Cost-Effective Synthesis of Vanadia Aerogels and Derivatives for Applications in Thermochromics, Energy Storage and Ballistics We have successfully fabricated vanadium oxide VOx aerogels using VOCl3 instead of VOOPr3, at a significantly reduced cost. Gels produced with this precursor have a nanoworm micromorphology identical to those fabricated using the alkoxide. Flame Synthesis of VOx and ZnO Nanoparticles The goal was to use a flame process to make metal oxide nanoparticles with unique morphology and to explore their conversion to hard nanoporous materials. Development and Study of Amine Sensors Based on Metal Nanoparticle-Doped Polyaniline The major part of this work was in the development and understanding of sensors made in a one-step green process. Regioselective Cross-Linking of Silica Aerogels with Magnesium Silicate Ceramics The VCU team developed a fabrication method, which allows one to mechanically reinforce aerogels ithout compromising their porosity since the core retains the characteristics of native aerogels.
