This article demonstrates the thermal properties of ZnO/aluminum‐doped ZnO and poly(3,4‐ethylenedioxythiophene):poly(4‐styrenesulfonate) (PEDOT:PSS) composite thin films. ZnO and AZO nanorods with diameters of 250 and 190 nm, respectively, were grown using the sol–gel technique. These NRs are incorporated into thin poly(3,4‐ethylenedioxythiophene):poly(4‐styrenesulfonate) (PEDOT:PSS) composite films. Al doping leads to a blue shift of the bandgap and a shift of the absorption edge to longer wavelengths. The thermal conductivity of the ZnO NRs/PEDOT:PSS composite was found to be in the range of 1.50–1.61 W/m·K over a temperature range of 273–353 K, while a significant reduction was observed in the case of AZO becomes /PEDOT:PSS composites due to phonon scattering.
