Their TE performance from 100K to 300K was systematically investigated. The maximum electrical conductivity of the composite polymer film reached up to 421S/cm when the film contained 10wt.% Bi2Te3, corresponding to the highest power factor of 9.9μW/m/K2, while their Seebeck coefficient fluctuated smoothly in a tiny range (14.2μV/K to 18.6μV/K). In addition, a relatively low thermal conductivity of 0.07±0.02W/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.
