Poly(3,4-ethylenedioxythiophene) : poly(styrenesulfonic acid) (PEDOT:PSS) composites were synthesized by Fe3+ catalyzed oxidative polymerization, and were prepared conducting films. We study the molecular weight effect of polymeric surfactant as PSS in PEDOT:PSS composite films. In addition, we used different PSS with 75000,200000, and 700000 Molecular weight at fixed ratio of PEDOT:PSS(1:2.5). Each with a different molecular weight of the synthesized PEDOT:PSS solution coated on glass substrate by spin coating method. Surface morphology of different samples was analyzed by AFM. Furthermore, Chemical structure of various composite samples was confirmed by FT-IR,and XPS. The electrical conductive property of PSS controlled composite films were checked by Van der pauw and 4-point probe method. |
