  • Abstract

A new material poly-silk peptide was fabricated using the electropolymerization of Silk Peptide (SP) on the surface of a Carbon Paste Electrode (CPE) for the first time. The morphological feature of poly-silk peptide film was characterized by Scanning Electron Microscopy (SEM). The preparation conditions such as SP concentration, supporting electrolyte pH and scan cycles were optimized. A stable poly- silk peptide film could be obtained with scanning 16 cycles in pH7.4 Phosphate Buffer Solution (PBS) containing 0.6 g⋅L^{-1} SP between -0.5 and +1.5V. In addition, a well-defined pair of oxidative and reductive peaks of poly-silk peptide was observed in 0.1M H_2SO_4 solution (pH 1.1), resulting from the successive redox reaction of -OH, -C=O and -COOH groups on poly-silk peptide.
