背景情况:

合聚电解质 (CPE) 是具有离子组的有机半导体.
对于CPE的水溶性,限制了它们在水性薄膜应用中的使用.
开发稳定的CPE电极用于水性电解质对于先进的设备至关重要.

研究的目的:

从水溶性阳离子CPE (CPE-K) 制造不溶性的固态伪电容电极.
为了研究CPE-K薄膜在水性电解质中的结构和可溶性变化.
为了评估CPE-K薄膜电极的电化学性能和稳定性.

主要方法:

从水中滴滴造CPE-K,以形成薄膜.
用X射线衍射和动态光散射进行结构和粒子大小分析.
电化学测试,包括电容测量和在各种电流密度下循环稳定性的测试.

主要成果:

从水中造的CPE-K薄膜形成不溶性,单元伪电容电极.
增加的KCl度导致更紧密的链间接触和静电选,增强不溶性.
在500 A g-1时,CPE-K电极保持85%的电容,在10万次循环后保持93%.

结论:

溶于水的离子有机材料,如CPE-K,可以通过增加电解质度,使其在水性电解质中不溶.
这一策略使得CPE在水性环境中可用于需要快速电子和离子传输的应用.
这些发现为电池,有机电化学晶体管和电化学传感器中的CPE提供了可能性.
