    Study on the Elcetric Conductity of Polyglycol-Poly(vinyl acetate)-Salt Complex Membrane

      摘要
    • 摘要: 采用PEG/PVAc复合物作为高分子固体电解质的基质材料,PEG/PVAc<1/1(mol)时两者有较好的混溶性并破坏了PEG的结晶。研究了高氯酸盐对PEG/PVAc复合膜导电率的影响,结果是随着盐浓度的增加,导电率增大,在同一盐浓度下电导率依次Y(ClO_4)_3>Nd(ClO_4)_3>LiClO_4>NaClO_4,首次将稀土盐用于高分子固体电解质,得到了较高的室温电导率(10~(-6)s·cm~(-1))。加入添加剂以及提高温度和湿度,均能提高复合膜的导电率。

       

      Abstract: The composite of polyglycol (PEG) and poly(vinyl acetate) (PVAc) (1/1 (mol)) has been used as the matrix for the polymer electrolyte. The results of DSC, X-ray and SEM showed that the crystallinity of PEG could be destroyed perfectly by PVAc. The rare ear
