The invention discloses a method for obtaining high-performance
polyaniline base
thermoelectric materials. The method comprises the following steps: (1) mixing
polyaniline powder with
ammonia water solution, carrying out stir, filter and
drying, and obtaining eigen-state
polyaniline, (2) mixing the polyaniline with
sulfonic acid, carrying out
grind, and obtaining polyaniline doped with the
sulfonic acid, (3) dissolving the polyaniline doped with the
sulfonic acid in
phenol solvent, carrying out stirr, and obtaining polyaniline solution, and (4) adding nanocarbon materials in the polyaniline solution, carrying out stir in a full mode, removing the
phenol solvent, and obtaining the high-performance polyaniline base
thermoelectric materials. According to the method for obtaining the high-performance polyaniline base
thermoelectric materials, the order degree of polyaniline molecular chain arrangement is firstly improved through interaction of the
phenol solvent and polyaniline molecules, then through composition with the
nano carbon composite materials, the order degree of the polyaniline molecular chain arrangement is further enhanced, and the high-performance polyaniline base thermoelectric materials are obtained. Therefore, ZT values of the polyaniline base thermoelectric materials and ZT values of block-shaped materials can be respectively improved by 0.5 and 0.05.
