纳米填料上的吸附物质是影响聚合物纳米复合材料性能的最重要因素之一。在此,我们系统地研究了通过合成方法引入的残留表面活性剂对聚苯乙烯/金纳米粒子纳米复合材料的玻璃化转变温度(Tg)的影响。发现表面活性剂会导致限制在金上的聚苯乙烯的Tg 明显降低。此外,我们使用偶极过滤 1H 固态核磁共振来表征金上限制的分子的迁移率。表面活性剂一旦吸附在金纳米颗粒上就不可能完全去除;因此,选择合适的合成方法很重要,并且应特别注意纳米填料上的吸附物质。
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.
