Dielectric investigation of nanocomposites based on Poly(methyl methacrylate) and Polyhedral Oligomeric Silesquioxanes — •Purv Purohit and Andreas Schönhals — BAM Bundesanstalt für Materialforschung und -prüfung, Unter den Eichen 87, 12200 Berlin, Germany

Enhancement of polymer properties by use of different types of nano-sized fillers is explored continuously from nearly past two decades. Polymer based nanocomposites have shown remarkable improvement in properties as compared to conventional scaled composites because of the length scale of interaction of the nanofillers with the polymer segments. Perseverant efforts are made to fully understand the structure-property relationship of such polymer based nanocomposites. Nanocomposites of Poly(methyl methacrylate) as matrix and MethacrylPOSS (MPOSS) as the nanofiller were prepared. The structure-property relationships of the nanocomposites were analyzed using dielectric spectroscopy. The change in the dynamic glass transition of the polymer with different concentrations of the nanofiller is investigated. Fourier transform infrared spectroscopy and differential scanning calorimetry were used to further investigate the properties of such nanocomposites.
