Abstract

N-Hydroxyethylcarbazole (EtOHCz) was electropolymerized on carbon fiber microelectrodes (CFMEs). The poly EtOHCz-modified CFME was characterized with FTIR-ATR scanning electron microscopy, cyclic voltammetry, and electrochemical impedance spectroscopy. The polymer/CFME electrode exhibited the capacitive behavior and also good stability up to 2,0 V. The presence of hydoxylic group Of the monomer seems to be an advantage on polymerization because of the unpaired electrons of oxygen, which would make ease at first stage for the adsorbtion on carbon fiber. The estimated value of the low-frequency redox capacitance (C-LF) was found to increase with increasing dc potential. (C) 2009 Wiley Periodicals, Inc. J Appl Polym Sci 113: 136-142, 2009
