(3,4-Ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), a representative conducting polymer, is environment-friendly and offers easy processing and flexibility owing to its hydro-dispersive properties. In this study, we investigated the electrical properties of PEDOT:PSS films with H₂SO₄/DMSO post-treatment. PEDOT:PSS is an electrolyte complex that has been attracting attention as a next-generation transparent electrode. The PEDOT:PSS films are composed of two heterogeneous phases: a PSS-rich layer and a PEDOT-rich layer. The PSS-rich layer is observed to be a homogeneous phase that does not influence the electrical properties. Thus, the PSS-rich layer, which occupies a large area of the PEDOT:PSS films, was removed to obtain films having high electrical properties. Both the layers exhibit a homogeneous phase regardless of their electrical properties. In particular, the PSS-rich layer without the PEDOT chains does not affect the electrical properties, since it does not contribute to hole transport. The heterogeneity of the PEDOT:PSS films with good electrical properties has been revealed by eliminating the unnecessary PSS-rich layers. The highest electrical conductivity obtained was 2239 S cm⁻¹, which is about 4.1 times higher than that of the pristine PEDOT:PSS films, for the films involving 15 M H₂SO₄/DMSO post-treatment.

PEDOT：PSS薄膜中异质聚合物层的电学特性

（3,4-Ethylenedioxythiophene）：poly（苯乙烯磺酸盐）（PEDOT：PSS）是一种代表性的导电聚合物，由于其水分散性，因此对环境友好且易于加工且具有柔韧性。在这项研究中，我们研究了具有H ₂ SO ₄的PEDOT：PSS薄膜的电性能/ DMSO后处理。PEDOT：PSS是一种电解质复合物，已作为下一代透明电极受到关注。PEDOT：PSS薄膜由两个异相组成：富PSS层和富PEDOT层。观察到富含PSS的层是不影响电性能的均匀相。因此，去除了占据大面积的PEDOT：PSS膜的富含PSS的层，从而获得了具有高电性能的膜。不论它们的电性能如何，这两个层均表现出均相。尤其是，没有PEDOT链的富含PSS的层不会影响电性能，因为它不会有助于空穴传输。PEDOT的异质性：通过消除不必要的富含PSS的层，已揭示出具有良好电性能的PSS膜。获得的最高电导率是2239 S cm对于涉及15 MH₂ SO₄ / DMSO后处理的膜，^-1，比原始的PEDOT：PSS膜高^-1倍。
