摘要：研究了含LiClO_4盐的聚氧化烯(PEO)400与环氧树脂所形成的互穿网络系统的非晶高分子膜的电导率随压力(0～40 MPa)的变化.温度由室温至70℃,电导率在5MPa下电导率对压力变化的等温曲线上出现一极大值,超过5MPa以后,电导率随压力的增加而减小.计算了激活体积,从结晶化学原理和离子沿最小能量途径迁移原理并考虑离子传输通道的微观物理图像解释了压力对样品的电导率和激活体积的影响.
Ionic conductivity of epoxy resin-polyethylene glycal (PE0400) interpenetrating polymer networks (IPN) containing lithium perchlorate between 25-70℃ under pressure from 0 to 40 MPa was investigated. The conductivity maximum exists near 4-5 MPa on conductivity versus pressure curve for these amorphous films. Over 5 MPa the conductivity decreased with increasing pressure. The effect of pressure on the activation volume is determined. For pressure dependence of conductivity and activation volume a microscopic explanation was obtained by considering the crystal picture of ionic transport passages according to crystal chemistry.
