“This paper reports a new biocompatible conductivity enhancement of poly (3,4 ethylenedioxythiophene):poly (styrene sulfonate) (PEDOT:PSS) films for biomedical applications. . . . The key to conductivity enhancement was the structural rearrangement of PEDOT:PSS, which was determined using atomic force microscopy, X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, and ultraviolet–visible spectroscopy. It was found that PEDOT inter-bridging occurred as a result of the structural rearrangement. Therefore, the conductivity increased on account of the continuous conductive pathways of the PEDOT chains.” MORE
