摘要The thermoelectric performance of free-standing poly(3,4-ethylenedioythiophene): poly(styrenesulfonate) (PEDOT:PSS) thin films deposited from aqueous dispersion treated by different concentrations of urea are investigated in detail. The electrical conductivity, Seebeck coefficient and power factor of PEDOT:PSS films versus temperature are determined, respectively. It is found that both the electrical conductivity and Seebeck coefficient of PEDOT:PSS films are enhanced after treatment with urea. Conductivity could be enhanced from 8.16 to 63.13 S⋅cm−1, the Seebeck coefficient is increased from 14.47 to 20.7 µV⋅K−1 and the power factor is rises to 2.7 µW⋅m−1K−2 at 300 K.
