Using an ARES Rheometer to investigate the β-relaxation change of graphene poly(ethyl methacrylate) nanocomposite
Here we describe the application of an ARES Rheometer (TA Instruments) with a rectangular torsion fixture, to investigate the β-relaxation change of poly (ethyl methacrylate)/ graphene oxide. It is observed that graphene increases both the glass transition and the β-relaxation temperature, but the β-relaxation to a lesser extent.
