▎ 摘 要
Graphene based polymer composites have emerged as a frontier field of research in recent years. Mechanical, thermal and electrical properties are reported to be significantly improved on addition of this carbonaceous material in polymers. On the other hand ethylene vinyl acetate copolymer is an important conventional polymer to be used in different fields. But poor thermal stability and weak flame retardancy limit the use of this polymer in wider fields. The present investigation therefore, reports the fabrication of reduced graphene oxide GR/EVA composites at varying wt % of GR content by solution mixing method to improve the above properties. XRD and SEM are employed to study the morphology of the composites. Thermal stability and flame retardancy of the composites were studied by thermogravimetric (TG) analysis and limiting oxygen index (LOI) test respectively. Under identical condition composite shows better thermal stability and an increase of similar to 70% of LOI value in the composite with only 0.75% of GR content than that of pristine EVA.
