Effect of polypyrrole on electrochemical properties of MWCNTs films prepared by DC-EPD technique / Nur Amira Jaaffar

Supercapacitors have emerged with the potential to enables major advance for energy storage. It is attractive applications where it has high energy density, fast charge- discharge time and high specific capacitance. Multi-walled carbon nanotubes (MWCNTs) usually used as electrode materials for super...
