Abstract
Graphene/Polyvinyl alcohol (PVA) nanocomposite was synthesized with a graphene content of 1wt%. Viscoelastic properties were studied using a Dynamical Mechanical Analyzer. The composite showed a higher storage modulus as compared to PVA up to 275K. Thereafter there was a crossover to a lower value. The glass transition temperature for the composite was found to be smaller by 26K than that of pure PVA. This is believed to be occurring because of a reduction of surrounding entanglements of the polymer molecules due to the presence of graphene sheets.
