We examine the neuromorphic behavior of organic electrochemical transistors (OECTs) based on polymer blends of a mixed conductor (PEDOT:PSS) and an ion conductor (PSSNa). We show that the addition of an ionic conductor into PEDOT:PSS decreases the information retention time in paired-pulse depression (PPD) experiments and speeds up the response in dynamic filtering experiments. Detailed studies of transient properties demonstrate that the relevant time scales for the neuromorphic response are determined by an ion injection in and an extraction out of the film. These results bring to the forefront OECTs as devices with neuromorphic properties that are readily engineered.
