▎ 摘　　要

The polymer nanocomposites samples of the poly (methyl methacrylate) (PMMA)-poly (vinylidene fluoride-trifluoroethylene) P(VDF-TrFE) with graphene oxide (GO) were prepared by solution casting method. The impact of GO on electroactive polar beta-phase of PMMA + P(VDF-TrFE) was investigated through the Fourier transform infrared spectroscopy (FTIR) and atomic force microscopy. The mechanical properties of nanocomposites samples have been investigated by measurement of microhardness. The value of microhardness and indentation depends on applied load on samples. The experimental result suggests that mechanical properties of samples decrease in presence of GO due to decrease in uniaxial orientation or agglomeration of GO. Surface characteristics such as surface free energy, interfacial free energy and hydrophobicity were determined by measuring the contact angle.
