The lower material and manufacturing costs of conductive polymers, particularly PEDOT:PSS, compared to indium tin oxide have led to significant research into their use in optoelectric devices. In this study, improvements of the electrical properties of PEDOT:PSS and PEDOT:PSS/Tween 80 via the production of multilayered films were investigated. A single layer of pristine PEDOT:PSS was found to give a sheet resistance of 1639 Ω□^–1. The application of an additional three layers reduced this value to 29 Ω□^-1, corresponding to an increase in conductivity from 2.6 to 18.3 Scm^–1. A similar trend was also found with formulations containing Tween 80. X-ray diffraction and Raman spectroscopy showed that the additional layers increased the crystalline order and induced a slight benzoid to quinoid shift. Surface profiling showed progressive increases in surface roughness with each additional layer of pristine PEDOT:PSS; however, this was mitigated by the presence of Tween 80 in the formulations.

与氧化铟锡相比，导电聚合物（尤其是 PEDOT:PSS）的材料和制造成本较低，因此人们对其在光电器件中的应用进行了大量研究。在本研究中，研究了通过生产多层薄膜来改善 PEDOT:PSS 和 PEDOT:PSS/Tween 80 的电性能。发现单层原始 PEDOT:PSS 的方块电阻为 1639 Ω□ ^–1。附加三层的应用将该值降低至29 Ω□ ^-1，对应于电导率从2.6 增加到18.3 Scm ^–1。含有 Tween 80 的配方也发现了类似的趋势。X 射线衍射和拉曼光谱表明，附加层增加了晶序并引起轻微的苯甲酰向醌型转变。表面轮廓显示，每增加一层原始 PEDOT:PSS，表面粗糙度都会逐渐增加；然而，配方中 Tween 80 的存在缓解了这一问题。
