Abstract
Conductive polymer materials are widely used in biomedical devices due to their properties of chemical doping, micro-nano processing, and surface biochemical modification. Polypyrrole (PPy) has good electrical conductivity and has excellent chemical stability, which shows terrific advantages in the neurogenic electrode. By modifying the electrode surface with doped ions, a coating with high roughness, low impedance, and high charge implantation can be constructed, effectively improving the device’s performance. In this paper, pyrrole is doped with p-toluenesulfonic acid (TsOH). PPy with different deposited charge densities is modified on ITO glass by controlling the reaction time to explore its influence on the electrochemical performance of ITO glass. The results show that PPy doped with TsOH is used to modify ITO glass, significantly improving its electrochemical performance. Furthermore, as the deposition time of pyrrole increases, the charging capacity density of the adjusted ITO glass increases, and the impedance is also lower.
