Synthesis and characterization of manganese oxide thin films as novel electrode material for electrochemical devices

Thin films of tetrapropylammonium manganese oxide (TPA-MO) were deposited on stainless steel foils as a supporting substrate by electrophoretic deposition (EPD) and pulsed electrodeposition (PED) techniques of preformed TPA-MO nanoparticles in stable colloidal suspensions. TPA-MO/Graphite nanocompo...
