Abstract

In this paper, we present the annealing effect on thermal diffusivity of Emeraldine Base−Polyaniline (EB). The thermal diffusivity was measured at room temperature using photoflash technique. The excitation source used consists of a high intensity camera flash. A series of samples annealed at different temperature (25 °C, 100 °C, 150 °C, 200 °C, 250 °C and 300 °C) were investigated and the annealing effect on the thermal diffusivity was discussed in detail. The Scanning Electron Microscopy (SEM) and X−ray Diffraction (XRD) measurement was done to analyze the annealing effect on morphology and sample structure.
