摘要： The topographical characterization showed that different levels of roughness can be obtained by varying the currents densities of film deposition. Furthermore, the films formed with current densities of 0.4 mA/cm2 showed superior electrical performance compared to the higher currents densities evaluated in this work. The adhesion and proliferation of SH-5YSY cells on the surface of these films indicated the cytocompatibility of this material and no toxicity was detected. Thus, cell attachment was preferred on the PEDOT:PSS films formed using the low current density. Designing an optimized electrode coating material will require a trade-off between desired electrical, morphological, chemical and biological properties.
