Title:
SANDWICH-LIKE MANGANESE DIOXIDE/POLYANILINE COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/169104
Kind Code:
A1
Abstract:
The present invention relaters to a sandwich-like manganese dioxide/polyaniline composite material and a preparation method therefor, belonging to the field of novel energy materials. Aniline is dissolved in an organic solvent to obtain an aniline organic solution; potassium permanganate is dissolved in deionized water to obtain an aqueous potassium permanganate solution, and the pH value of the aqueous potassium permanganate solution is controlled; a low-temperature pretreatment is performed on the two solutions respectively; the aqueous potassium permanganate solution is introduced to the surface of the aniline organic solution, forming a two-phase interface and is reacted for 12-48 hours under conditions of 0-4°C; and the product is filtered, washed and dried to obtain the sandwich-like manganese dioxide/polyaniline composite material. Under acidic conditions, oxidized and polymerized polyaniline has a very high conductivity, and at the same time, the polyaniline is positioned between manganese dioxide slice layers, so that the agglomeration thereof is effectively prevented, and the performances, such as the high specific capacitance, are greatly developed, laying the foundation for applications thereof in electrode materials for super-capacitors.
