论文摘要

我们研究了在几何限制下,电荷转运动力学的差异(3,4-乙基二苯乙烯)(PEDOT)衍生物的电导率增强的差异。聚合物混合聚合物聚(3,4-乙基二氧化噻吩)的结果:聚(苯二甲酸酯)和聚合物知识分子混合物,聚(3,4-乙基二氧噻吩):甲二甲酸盐):甲二酸酯,强调这些系统在凝结中的座位和处理条件的作用。特征尺寸的狭窄几何形状中的盛行运输长度尺寸源自这些聚合物系统中的不同障碍。通过分子水平重组引入的两个不同的PEDOT的这些可观察到的差异可用于调整导电聚合物系统,以实现有效的电气和热电性能。聚合物系统的电导率σ在分子水平和连通性参数下是电子结构的函数,已在各种通道直径的圆柱 - 氧化铝纳米镜头中进行了探测,在不同的频率ω和温度下,观测值也强调了这些导电性疾病在这些传导polymer系统中的作用。

We study the differences in electrical charge transport dynamics of the conductivity enhancement of poly(3,4-ethylenedioxythiophene) (PEDOT) derivatives under geometrical confinement. The results of polymer blend poly(3,4-ethylene dioxythiophene):poly(styrenesulfonate) and a polymer-monomer blend, poly(3,4- ethylenedioxythiophene):tosylate, highlight the role of dopants and processing conditions of these systems under confinement. The prevailing transport length scales in confined geometry of characteristic dimensions originate from varying disorder in these polymer systems. These observable differences in two different PEDOTs introduced by molecular level reorganization can be utilized to tune conducting polymer systems for efficient electrical and thermoelectric properties. The electrical conductivity σ of the polymer system, which is a function of the electronic structure at molecular level and a connectivity parameter, has been probed in cylindrical-alumina nanoscaffolds of various channel diameters, at different frequencies ω and temperatures T. The observations also emphasize the role of disorder in these conducting polymer systems.
