Description

ABSTRACT

The vapor barrier film of epoxy graphene nanocomposites of 0.75 and1.5wt% was synthesized by dispersion method.This dispersion of graphene mainly attributes to the excellent water barrier property. When epoxy combined with graphene nanoparticles show significantly increased toughness and dampness capacity of epoxy system.This is mainly due to free volume reduction respect to the pristine polymer. The nanocomposites derived from graphene show excellent electrical, thermal and mechanical properties.  The excellent electron transport, high surface area and mechanical properties of graphene epoxy nanocomposites has potential applications in food packaging, anticorrosive coating. The synthesized barrier film of epoxy graphene composites were characterized by differential scanning calorimetric techniques (DSC ). The barrier properties were investigated by using electrochemical impedance spectroscopy (EIS).
