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。
Adopting PEG / PVAc composite as the matrix material of polymer solid electrolyte, the PEG / PVAc <1/1 (mol) have better miscibility and disrupt the crystallization of PEG. The effects of perchlorate on the conductivity of PEG / PVAc composite films were investigated. The results showed that the conductivity increased with the increase of salt concentration. The conductivity of the films was Y (ClO_4) _3> Nd (ClO_4) _3 > LiClO_4> NaClO_4, the rare earth salt was firstly used in polymer solid electrolyte, and higher room temperature conductivity (10 -6 s · cm -1) was obtained. Add additives and improve the temperature and humidity, can improve the conductivity of the composite film.
