Electrophoretic deposition of manganese oxide films

Electrophoretic deposition method has been developed for the fabrication of manganese oxide films for applications in electrochemical supercapacitors. Submicrometre particles of manganese oxide were obtained by reduction of KMnO 4 solutions with ethanol. As prepared particles were amorphous and crystallised in a birnessite structure after annealing at 400°C during 1 h. The use of sodium alginate as a dispersant, enabled electrosteric …
