摘要:
为探究微量改性剂氧化石墨烯对聚酯结构性能的影响,以PTA和EG为单体,氧化石墨烯为改性剂,采用直接酯化原位聚合法得到改性聚酯。通过红外光谱、热重和差示扫描量热法等测试方法来分析表征改性试样的结构、结晶性能和热稳定性。结果表明:在聚合反应过程中,氧化石墨烯与聚酯大分子间并未形成新的官能团;在280~310 ℃加热过程中,添加氧化石墨烯的改性聚酯试样,改性试样热失重量均小于未改性聚酯;当改性剂氧化石墨烯添加量为10 -5 wt%、10 -4 wt%时,试样的熔点、结晶温度和结晶度均出现不同程度的升高,结晶度分别升高了153%和169%。因此添加少量氧化石墨烯改性剂,有助于提升聚酯的结晶性能,并能提高聚酯材料在加工成型过程中的热稳定性。该研究结果可为提高聚酯材料的品质提供参考。
