     free-standing poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (pedot: pss)/bi2te3thermoelectric (te) composite films have been successfully prepared by a simple physical mixing method with different contents of bi2te3. x-ray diffraction (xrd) and scanning electron microscopy were used to analyze the phase composition and microstructure of the composite films. their te performance from 100 k to 300 k was systematically investigated. the maximum electrical conductivity of the composite polymer film reached up to 421 s/cm when the film contained 10 wt.% bi2te3, corresponding to the highest power factor of 9.9 μw/m/k2, while their seebeck coefficient fluctuated smoothly in a tiny range (14.2 μv/k to 18.6 μv/k). in addition, a relatively low thermal conductivity of 0.07 ± 0.02 w/m/k has been obtained. the maximum figure of merit of the composite reached up to 0.04 at room temperature, which is a relatively high value in the organic te field.
