A novel polyester/graphene nanocomposite fiber was produced using the in situ polymerization protocol with carboxylated graphene and melt spinning technology. The resulting nanocomposite fibers were characterized by X-ray diffraction (XRD), Raman spectroscopy, differential scanning calorimeter (DSC), and scanning electron microscope (SEM). The fibers containing 0.2 wt% graphene fraction showed an excellent dispersity of graphene nanosheets in polymeric matrix. DSC test showed that the efficient polymer-chain grafting depresses the crystallization of PET chains. This graphene-contained PET fabric exhibited attractive antibacterial properties that can be employed in fruit preservation to ensure food safety.
采用原位聚合法，以羧基化石墨烯和熔体纺丝技术制备了一种新型聚酯/石墨烯纳米复合纤维。通过X射线衍射（XRD）、拉曼光谱、差示扫描量热仪（DSC）和扫描电子显微镜（SEM）对所得纳米复合纤维进行了表征。含有0.2 wt%石墨烯组分的纤维显示出石墨烯纳米片在聚合物基体中的优异分散性。DSC测试表明，有效的聚合物链接枝抑制了PET链的结晶。这种含石墨烯的PET织物表现出有吸引力的抗菌性能，可用于水果保鲜以确保食品安全。
