Abstract
A soluble conducting polymer, poly(3,4-ethylenedioxythiophene) (PEDOT), has been prepared in various synthetic conditions. The physical properties of a resulting polymer, such as molecular weight, electrical conductivity, solubility, and optical property, were monitored with the variation of polymerization solvent, oxidant and reaction time. An increase in themolecular weight with reaction time was ovserved and the best results in the solubility and conductivity was obtained using methanol and ferric toluenesulfonate as a solvent and an oxidant, respectively. In the case that PEDOT was in chloroform solution, the optimum physical properties were obtained: The solubility reached up to > 90 % and the conductivity of the cast film was 1.85 S/cm.

가용성 전도성 고분자인 poly(3,4-ethylenedioxythiophene)(PEDOT)을 다양한 중합 조건에서 제조하였다. 중합시 사용된 용매와 개시제 및 중합시간의 변화에 따른 PEDOT의 분자량, 전기 전도도, 용해도 및 광학성질 등을 관찰하였다. 중합시간이 길어질수록 분자량이 증가하였으며, 메탄올과 ferric toluenesulfonate를 용매와 개시제로 사용할 경우 가장 높은 용해도와 전기 전도도를 나타내었다. PEDOT의 용해시는 chloroform을 용매로 사용할 경우에 가장 좋은 물성을 얻을 수 있었다. 이때, 용해도는 90% 이상을 나타내었으며, 용액 주조한 필름의 전기 전도도는 1.85 S/cm의 값을 나타내었다.
