摘要：

Polymer electrolytes, based on a blend of poly(methylmethacrylate) [PMMA]/poly(vinylidene difluorid-co-hexafluoropropylene)[P(VdF-HFP)], were prepared by electrospinning at room temperature. The morphology, structure, ionic conduction and mechanical properties of the electrospun membranes were characterized by atomic force microscopy (AFM), FTIR spectra, X-ray diffraction (XRD), electrochemical impedance spectroscopy (EIS) and mechanical measurements. The composites showed the ionic conduction and uptake and leakage behaviors of the electrolyte solution were improved by the addition of PMMA. Also, the mechanical property of the blend membranes was better than that of the pure P(VdF-HFP) electrospun membranes. (c) 2008 Elsevier B.V. All rights reserved.
