| PEDOT | |
| In this work, electropolymerizations of PEDOT in aqueous solution were carried out. Nanometric graphite layers (NGL) deposited on glass were used as the electrodes. Counterions such as dodecyl sulfuric acid (DSA) [2], 4-dodecylbencenesulfonic acid (DBSA) [3] or polystyrene sulfonic acid (PSS) [3] were evaluated to study their effect on PEDOT morphology and electrical conductivity. PEDOTs´ morphology was characterized by atomic force microscopy (AFM) and scanning electron microscopy (SEM), and electrical properties by electrochemical impedance spectroscopy (EIS). Microscopy techniques showed that the longer the counterion alkyl chain, the greater the particle size and the greater film thickness. According to this, PEDOT:DBSA films presented the largest particle size and thickest films and also the best conduction in comparison with PEDOT:PSS or PEDOT:DSA. | |
