In the present article, a theoretical and experimental investigation is done to explore the polarization behavior of composite fibers based on copolymer poly-trifluoroethylene P(VDF-TrFE) and graphene oxide (GO) with varying composition of the components is explored for its possible application in bioelectronic devices. Electromechanical properties of the PVDF\/GO nanofibers were investigated using piezoresponse force microscopy (PFM) method. The switching behavior, charge states, and piezoelectric response of the fibers were found to depend on the concentration of GO up to 20%. Theoretical models of PVDF chains, interacting with Graphene\/GO layers has been used to explore the evolution of piezoresponse in the composite fibers. In order to compute piezoelectric coefficients, the behavior of composite in electrical fields has been modeled using software HyperChem. The experimental results are qualitatively correlated with a computed theoretical model.<\/jats:p>","DOI":"10.3390\/c5030048","type":"journal-article","created":{"date-parts":[[2019,8,13]],"date-time":"2019-08-13T04:31:21Z","timestamp":1565670681000},"page":"48","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Preparation, Stability and Local Piezoelectrical Properties of P(VDF-TrFE)\/Graphene Oxide Composite Fibers"],"prefix":"10.3390","volume":"5","author":[{"given":"Maxim","family":"Silibin","sequence":"first","affiliation":[{"name":"Institute of Perspective Materials and Technologies, National Research University of Electronic Technology, 119991 Moscow, Russia"},{"name":"Institute for Bionic Technologies and Engineering, I.
