采用注射成型法制备了聚己内酯（PCL）/还原氧化石墨烯（RGO）纳米复合棒，研究了RGO对PCL基体的影响。差示扫描量热仪和偏光显微镜的结果表明，RGO是一种有效的PCL成核剂。二维广角X射线衍射结果表明，RGO的引入提高了PCL晶体在流动方向上的取向度，且不影响PCL的晶体结构。二维小角X射线散射结果证实，随着RGO含量的增加，PCL链在流动方向上的取向增强，这归因于RGO阻碍了聚合物链的运动。这些结果表明，RGO的引入可以促进PCL基体的结晶和取向，这是提高力学性能的主要因素。
Poly(ε-caprolactone) (PCL)/reduced graphene oxide (RGO) nanocomposite bars were prepared by injection molding, and the effects of RGO on the PCL matrix were investigated. Differential scanning calorimeter and polarized optical microscopy results demonstrated that RGO was an effective nucleation agent for PCL. Two-dimensional wide angle X-ray diffraction results showed that the incorporation of RGO can enhance the orientation degree of PCL crystals in the flow direction and did not influence the crystal structure of PCL. Two-dimensional small angle X-ray scattering results confirmed that the orientation of PCL chains in the flow direction was enhanced with the increase of RGO content, which was attributed to that RGO obstructed the motion of polymer chains. These results indicated that the incorporation of RGO can enhance the crystallization and orientation of PCL matrix, which was the major factor for the improvement of mechanical properties.
