Preparation, characterization and microhardness measurements of hybrid nanocomposites based on PMMA + P(VDF–TrFE) and graphene oxide

Abstract

The polymer nanocomposites samples of the poly (methyl methacrylate) (PMMA)— poly (vinylidene fuoride–trifuoroethylene) P(VDF–TrFE) with graphene oxide (GO) were prepared by solution casting method. The impact of GO on electroactive polar β-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.
