Method for manufacturing conductive polyaniline nanotube by using xylitol as template

The invention discloses a method for manufacturing a conductive polyaniline nanotube by using xylitol as a template. The method comprises the steps that a certain amount of xylitol is sufficiently dissolved into deionized water, purified aniline and 10 mL of a 1 mol/M hydrochloric acid solution are added into an ice-water bath, an oxidative initiator of ammonium persulfate is added dropwise after sufficient stirring is performed so as to initiate polymerization of the aniline, and the reaction is performed for 12 h on the stirring condition to obtain a conductive polyaniline material of the tubular structure. The method is simple in preparation process, environmentally friendly, reliable, wide in raw material sources, low in cost and suitable for industrial production, the obtained conductive polyaniline nanotube has the higher specific capacitance and the larger current resistance compared with polyaniline prepared with no template, and the conductive polyaniline nanotube is an ideal supercapacitor electrode material.
