제목 The Effect of New Competitive Method for Highly Conductivity PEDOT:PSS Films
초록 Poly(3,4-ethylenedioxythiophene):Poly(styrenesulfonate) (PEDOT:PSS) with high transparency and superior mechanical flexibility is an excellent material as the transparent electrode to replace indium tin oxide(ITO). However, the pristine PEDOT:PSS films has a major problem of the low conductivity for commercial application. To resolve the low conductivity of PEDOT:PSS have been investigated the various methods using additives. In this work, we have tried to improve of low conductivity PEDOT:PSS by using New additive with multi-functional group. The conductivity of PEDOT:PSS films was significantly enhanced and depended on the amount of New additive at the same time. The mechanism for the conductivity enhancement of PEDOT:PSS with New additive is attributed to the phase separation of PSS chain from PEDOT:PSS. In other words, it is caused by conformations change of the PEDOT chains as the results of the compounds-induced reduction in the Coulombic attraction between the hydrophobic PEDOT and hydrophilic PSS chains.
