Synthesis And Characterization Of Polyaniline/Multiwalled Carbon Nanotubes Based Nanocomposites

Polyaniline/multiwalled carbon nanotubes-manganese dioxide (PANI/MWCNTs-MnO2) nanocomposites were synthesized and characterized. MnO2 filling in the cavities of the MWCNTs were successfully done with clean outer surface as seen by transmission electron microscope (TEM). Ammonium persulphate ((NH...
