A biodegradable copolymer was synthesized in our lab. The structure and molecular weight were determined through Fourier transform infra- red spectroscopy (FT-IR), proton nuclear magnetic resonance spectroscopy (1H-NMR), and multi angle light scattering spectrometry. Thermal and morphological properties were characterized using differential scanning calorimetry (DSC) and X-ray powder diffraction (XRD).
Carbon felt electrodes were used as a base material for the electrode of the biofuel cell. The carbon felt electrodes were dip coated with the polymer. Electroanalytical techniques such as cyclic voltammetry and electrochemical impedance spectroscopy were used to compare the conversion of glucose into electricity and electrochemical activity of the uncoated and coated electrodes. The results of this investigation showed that the coated electrodes confer compatibility to WSUCF1 and improved performance of the biofuel cell.
