Thermoelectric materials are a new type of functional material in which carriers migrate inside the solid to achieve direct conversion between heat and electricity. Inorganic thermoelectric materials currently have the best thermoelectric properties

but they have the disadvantages of being difficult to process

high in cost

and toxic. The organic thermoelectric materials are flexible and easy to process

rich in resources

low in cost

and environmentally friendly

thus gradually becoming the research focus of thermoelectric materials. Among them

polyaniline (PANI) is an excellent conductive polymer

which has attracted research interests due to its good thermoelectric properties. This mini-review introduces the research progress of PANI thermoelectric materials in recent years

and proposes its future development.
