Thermoelectric material (TE) is a kind of new environmental protection material that can direct conversion of heat energy and electric energy. Presently

inorganic materials are considered to be the best thermoelectric materials. However

scarce resource

high prices

and poor processability limit the large-scale industrialization of inorganic thermoelectric materials. Organic conducting polymers as thermoelectric materials have received increasing attention recently. Poly(3

4-ethylenedioxythiophene) (PEDOT) as thermoelectric materials has drawn extensive attention because of their excellent thermoelectric properties. In this review

we introduce some methods for improving the thermoelectric properties of PEDOT at first

and we discuss the recent thermoelectric properties development of PDEOT with its recent research progress.
