Primary Research Areas
Organic/inorganic nanocomposites are created via polymer-in situ sol-gel reactions for inorganic alkoxides. In one case, phase-separated morphologies of ionomers act as templates for in situ polymerizations so that inorganic, or organically-modified inorganic nanophases are grown within ionic domains. In another case, sol-gel reactions initiate at chemically-modified chain ends resulting in organic/inorganic coupling. The organic host ranges from elastomers to high Tg polymers and can be amorphous or semicrystalline. Molecular structures and morphologies are investigated over a range of dimensional scales using FTIR, NMR, and fluorescent probe spectroscopies by transmission, scanning and atomic force microscopies, and by thermal and mechanical methods. A MALDI-TOF-mass spectrometry is used to investigate polymer molecular weight/distribution and endgroup modification, inorganic modification of polymers, and polymer degradation. Dielectric relaxation/electrical impedance spectroscopy is used to study long/short range charge motions, diffusion in and degradation of, polymers. Gas and liquid permeation of polymers is evaluated within the context of membrane technology. The nanoscopic environments of these hybrid materials can be chemically tailored to impart gas/liquid permselectivity based on molecular size exclusion and/or molecular interactions.
