چکیده انگلیسی

Graphene oxide (GO) was incorporated into poly(butylene succinate) (PBS) via a solution coagulation method to fabricate PBS/GO nanocomposites. Scanning electron microscope and transmission electron microscope observations indicated that GO with exfoliated lamella dispersed in PBS uniformly and showed good interfacial adhesion with the PBS matrix. Differential scanning calorimetry analysis suggested that the crystallization ability of PBS first increased and then decreased with increase in GO content, due to the competitive nucleating effect and confined space effect with addition of exfoliated GO. Isothermal crystallization kinetics investigation showed that the overall crystallization rate of PBS first increased and then decreased with increasing GO content while the crystallization mechanism remained unchanged. Polarized optical microscopy analysis indicated that GO worked as an effective nucleating agent for PBS. X-ray diffraction characterization suggested that incorporation of GO did not change the crystal structure of PBS. Both tensile testing and dynamic mechanical analysis witnessed the reinforcement in mechanical performance of PBS by incorporation of GO.
