The adsorbed species on nanofillers is one of the most important factors that may influence the performance of polymer nanocomposites. Herein, we performed a systematic investigation of the effects of the residual surfactant introduced by a synthetic method on the glass transition temperature (Tg) of polystyrene/gold nanoparticle nanocomposites. The surfactant was found to cause an obvious decrease in theTgof polystyrene confined on gold. Furthermore, we used dipolar-filtered1H solid-state nuclear magnetic resonance to characterize the mobility of the molecules confined on gold. It was impossible to completely remove the surfactant once it had been adsorbed on the gold nanoparticles; thus it is important to choose suitable methods of synthesis, and special attention should be paid to the adsorbed species on nanofillers.
