制备了一种新型的夹芯聚合物膜，该膜由两层聚偏氟乙烯（PVDF）纤维膜和一层聚甲基丙烯酸甲酯（PMMA）膜组成。通过扫描电镜和X射线衍射对其特性进行了研究。该膜可以容易地吸收非水电解质以形成凝胶聚合物电解质（GPE）。所得凝胶聚合物电解质在室温下具有高达1.93×10−3Scm− 1的高离子电导率，并表现出4.5V（vs. Li/Li+）的高电化学稳定电位。它在聚合物锂离子电池中具有很大的应用潜力。
A novel kind of sandwiched polymer membrane was prepared, which consists of two outer layers of electrospun poly(vinyl difluoride) (PVDF) fibrous films and one inner layer of poly(methyl methacrylate) (PMMA) film. Its characteristics were investigated by scanning electron microscopy and X-ray diffraction. The membrane can easily absorb non-aqueous electrolyte to form gelled polymer electrolytes (GPEs). The resulting gelled polymer electrolytes had a high ionic conductivity up to 1.93×10−3Scm−1at room temperature, and exhibited a high electrochemical stability potential of 4.5V (vs. Li/Li+). It is of great potential application in polymer lithium-ion batteries.
