Schematic illustration of the proposed microzone galvanic cell reaction that occurs during the conversion from manganese oxide wire to polyaniline nanotube. a) The aniline was polymerized on a manganese oxide nanowire surface. b) The hollow structure developed mainly through the micro-zone galvanic-cell reaction mode. c) The homogeneous polyaniline tube was finally formed because the whole surface of the polyaniline (Polyaniline) thin film was almost equipotential in the micro-zone galvanic-cell reaction.
