采用静电纺丝法在室温下制备了聚甲基丙烯酸甲酯（PMMA）/聚偏氟乙烯-六氟丙烯共聚物（P（VdF-HFP））共混聚合物电解质。采用原子力显微镜（AFM）、傅立叶变换红外光谱（FTIR）、X射线衍射（XRD）、电化学阻抗谱（EIS）和力学性能测试等手段对电纺膜的形貌、结构、离子导电性和力学性能进行了表征。结果表明，PMMA的加入改善了复合材料的离子导电性和电解质溶液的吸收和泄漏行为。共混膜的力学性能也优于纯P（VdF-HFP）电纺膜。(c)2008 Elsevier B. V.保留所有权利。
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.
