Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)(PEDOT:PSS) has been widely used as an active channel component in organic electrochemical transistors (OECTs). Hygroscopic nature of PEDOT:PSS is beneficial for ion penetration resulting in the large current modulation in OECTs when operated with aqueous electrolytes or in air. In this work, we studied the charge transporting properties of PEDOT:PSS/cellulose blends. We observed that, when cellulose was blended, the on-current level increased by a factor of 10 from 1.2 mA to 12 mA. We also studied the effects of the compatibility between ionic liquids and celluloses on device performance by using the contact angle measurement and the electrochemical impedance spectroscopy (EIS). |
