摘要: Nanocomposites of poly (ethylene oxide) (PEO) and graphene were made in aqueous solution using an organic salt containing a carboxylate ion carboxylic acid group. The cation corresponding to the interacts with π electron clouds through cation–π interaction promotes exfoliation sheets. group modifier forms H-bonds PEO thereby improves interfacial adhesion. effect number carbon atoms present on its dispersing ability was investigated. It observed that there exists optimum respect level dispersion related nanocomposites as examined by scanning microscopy (SEM) transmission (TEM). mechanical properties having various concentrations evaluated compared theoretical values Halpin–Tsai model. crystallization behavior upon incorporation modified studied temperature modulated differential colorimetry (MDSC) discussed well. process used here is green it does not require any toxic solvent or hazardous material for modification graphene.
