TY - JOUR A1 - Hao, Ning A1 - Böhning, Martin A1 - Wohlrab, Sebastian A1 - Schönhals, Andreas T1 - Polymer Based Nanocomposites with PhenethylPOSS as Nanofilter Investigated by Dielectric Spectroscopy and Gas Transport Measurements N2 - Polyhedral oligomeric silsesquioxane with phenethyl substituents (PhenethylPOSS) as nanofiller was incorporated within Poly(bisphenol A carbonate) (PBAC) as matrix. Dielectric spectroscopy proved an almost complete miscibility of PhenethylPOSS up to 7 wt. %. At higher concentrations phase separation yields composites with a PBAC-rich matrix and POSS-rich domains which posses well shaped interfaces. The nanocomposites were also investigated with respect to their gas transport behaviour. An increase of the gas permeability was found at higher PhenethylPOSS concentrations, which is due to the phase separated structure.
