The Chemistry and Physics of the Interface Region and Functionalization



A description is given of the chemistry and physics of the interface region of polymer nanodielectrics, covering the formation of the nanoparticles, their functionalization, and the selection and use of coupling agents for covalent bonding to the polymer matrix. The main focus is on spherical inorganic nanoparticles dispersed into polymer melts and on natural and synthetic clays and micas and other layered inorganics which are intercalated or exfoliated before introduction of a polymer solution in a polar solvent or from the melt. The chemistry addresses the chemical structure of the nanoparticles and polymer, the bonding that is present, and the role of coupling agents and compatibilizers. The physics addresses the morphology, glass transition temperature, and free volume of the polymer nanocomposite; and interfacial polarization, dielectric relaxation, electron paramagnetic resonance, and modulated differential scanning calorimetric effects. The views of investigators on the understanding of the interface in this burgeoning field are presented and compared.
