Synthesis of polypyrrole/carbon nanotubes composite for supercapacitors applications

Synthesis and characterization of polypyrrole (PPy) layers were conducted in order to obtain a porous material whose electrochemical properties will be suitable for applications in supercapacitors. In order to improve PPy properties, it was combined with carbon nanotubes (CNTs). The electrochemical and pseudocapacitive properties of the prepared materials were investigated by cyclic voltammetry, electrochemical impedance spectroscopy and electrochemical quartz crystal nanobalance. The results show that PPy/CNTs composite had better pseudocapacitive properties compared to pure polypyrrole.
