Reactive Template Fabrication of Uniform Core-Shell Polyaniline/Multiwalled Carbon Nanotube Nanocomposite and Its Electrochemical Capacitance
Uniform core-shell PANI/MWCNT nanocomposite was synthesized by an efficient reactive template method based on the MnO2/MWCNTs as a template and an oxidant. Such nanocomposite presents a high specific capacitance of 296 F g(-1) at 2 A g(-1) and even 220 F g(-1) at 5 A g(-1) and long cycling stability (84% capacity retention after 1000 cycles), indicating a promising candidate for electrochemical capacitors.
