摘要: In this work, preparation, characterization and crystallization kinetics of two series of biodegradable nanocomposites of poly (ethylene succinate) containing graphene oxide [Poly (ethylene succinate)/Graphene Oxide (PESu/GO) nanocomposites] are investigated. Poly (ethylene succinate) biodegradable polyester was synthesized by melt polycondensation from succinic acid and ethylene glycol. Graphene oxide was prepared using a modified Staudenmaier method from of powdered graphite. Organomodified GO (Org-GO) was prepared by using 1-dodecylamine. PESu/GO and PESu/org-GO with GO or org-GO concentrations 0.5, 1 or 2.5 wt% were prepared by the solution mixing technique using DMF as solvent. The nanocomposites were characterized with SEM, TEM, WAXD, DSC, FTIR, and PLM. Microscopic study showed satisfactory dispersion of GO and org-GO. Isothermal and nonisothermal crystallization …
