Evaluation of thermomechanical properties of polyvinyl butyral nanocomposites reinforced with graphene nanoplatelets synthesized by in situ polymerization

In this work, polyvinyl butyral (PVB) nanocomposites reinforced with 0.5 to 2.5 wt % of graphene oxide (GO) and graphene nanoplatelets (GNP) were synthesized via in situ polymerization. Dynamic mechanical analysis showed that PVB/GO 2.5 wt % nanocomposites present the largest storage modulus, with increases of 10 °C in the PVB glass transition temperature. The degree of entanglement and the reinforcement efficiency factor ( C coefficient) were...
