But, depending on their compatibility with the polymer matrix, POSS moieties could either disperse almost within a molecular level or aggregate into nanoscale domains [19], because of less compatibility between polymer-rich and POSS-rich domains. Hence, the POSS fractions of polymer/POSS nanocomposites as well as the reduction of their dielectric constants are within certain limits [11]. Pbz/POSS nanocomposites exhibit featureless morphologies, with no discerbible phase separation suggesting that the POSS nanoparticles are dispersed homogeneously throughout the matrix [12]. |
