摘要

利用压电喷墨印刷技术沉积了PEDOT/PSS有机导电薄膜

研究了退火温度和乙二醇掺杂对薄膜导电性能的影响。实验结果表明:未退火和退火温度为120

140

160 ℃时

薄膜表面平均粗糙度分别为8.15

4.10

3.36

2.66 nm;乙二醇掺杂使导电激活能由未掺杂时的0.096 eV减小为0.046 eV;电导激活能减小表明PEDOT分子链从低电导率的卷曲构象向高电导率的伸展构象转变;此外

乙二醇掺杂促使PSS与PEDOT/PSS分离

使团聚的PEDOT/PSS颗粒变小从而分散更均匀

降低了表面粗糙度。

Abstract

Conducting polymer PEDOT/PSS films were deposited utilizing piezoelectric ink-jet printing technology. The effect of annealing temperature

ethylene glycol doped on conductive properties of the films was studied. The results show that the average surface roughness of films when no annealing and annealing at 120

140

160 ℃ were 8.15

respectively; ethylene glycol doped reduces the conductive activation energy of the film from 0.096 eV(no-doping) to 0.046 eV. The decrease of the conductivity activation energy suggests that the PEDOT chain turns from the coil conformation of low conductivity into the expanded-coil conformation of high conductivity. In addition

the doping of ethylene glycol reduces the surface roughness of the films due to PSS separated from PEDOT/PSS and then the PEDOT/PSS particles become smaller and more evenly dispersed.
