摘要: The unprecedented attributes such as biocompatibility and flexibility of macromolecular piezoelectric polymer has triggered an immense interested in scientific society for their potential exploitation implantable electronic devices. In the present article, a theoretical experimental investigation is done to explore polarization behavior composite fibers based on copolymer poly-trifluoroethylene P(VDF-TrFE) graphene oxide (GO) with varying composition components explored its possible application bioelectronic Electromechanical properties PVDF/GO nanofibers were investigated using piezoresponse force microscopy (PFM) method. switching behavior, charge states, response found depend concentration GO up 20%. Theoretical models PVDF chains, interacting Graphene/GO layers been used evolution fibers. order compute coefficients, electrical fields modeled software HyperChem. results are qualitatively correlated computed model.
