本文研究了极性基团浓度、碱金属盐阳离子和阴离子尺寸对均聚物聚环氧氯丙烷(PECH)和共聚物聚环氧氯丙烷-聚环氧乙烷(PECH-PEO)电导率的影响。对锂盐络合物,极性基团浓度增高,电导率降低。钠盐络合物则正好相反,极性基团浓度越高,电导率越高。碱金属盐阳离子和阴离子尺寸对聚合物离子导体电导率都有明显影响。所研究的聚环氧氯丙烷与三种碱金属盐络合物PECH-MI(M=Li,Na,K)的电导率数据表明,钠盐络合物的电导率最高,锂盐和钾盐络合物的电导率较低。碱金属盐阴离子越大,PECH络合物的电导率越低。此外,还发现制膜条件对薄膜电导率有影响。本文对上述结果作了详细的分析讨论。
In this paper, the effects of polar group concentration, alkali metal salt cation and anion size on the conductivity of homopolymer polyepichlorohydrin (PECH) and copolymer polyepichlorohydrin-polyethylene oxide (PECH-PEO) influences. For lithium salt complexes, the polar group concentration increases and the conductivity decreases. The sodium salt complex is the opposite, the higher the polar group concentration, the higher the conductivity. Alkali metal salt cation and anion size have a significant effect on the conductivity of polymer ionic conductors. The conductivity data of PECH-MI (M = Li, Na, K) of the studied polyepichlorohydrin complex with three alkali metal salts show that the conductivity of the sodium salt complex is the highest with lithium and potassium salts The conductivity of the complex is low. The larger the alkali metal salt anion, the lower the conductivity of the PECH complex. In addition, it was also found that membrane conditions have an effect on the conductivity of the membrane. This article made a detailed analysis and discussion of the above results.
