摘要：

For electrically conducting polypyrole films, the thermal diffusivity and thermal conductivity were obtained by modeling the signals from the photopyroelectric flash technique with a one-dimensional four-layer system. This method has a number of advantages over the sinusoidal excitation: wide thickness range, fast acquisition, simple and cheap setup. This first thermal characterization of polypyrole films shows an increasing thermal conductivity with dopant ion concentration.
