Abstract
The thermal diffusivity has been measured for the Polypyrrole-Polyethylene Glycol (PPy-PEG) composite films by the open photoacoustic method. The experimental data were analyzed for thermal diffusivity by fitting procedure. The different process parameters such as different concentrations of insulating polymer, monomer and electrolyte and the different voltages used to prepare the PPy-PEG composite films brought changes in thermal diffusivity. The process condition of 0.20 M pyrrole, 0.10 M p-toluene sulfonate and 1×10-3 M PEG at 1.20 volt (vs SCE) appeared as the optimum condition and the PPy-PEG composite film produced from this optimum condition shows the highest thermal diffusivity (7.88×10-7 m2 s-1).

Study is to investigate the thermal diffusivity as a function of process parameters such as different
We prepared the third series of polypyrrole-polyethylene glycol (PPy-PEG) composite film by keeping the concentration of PEG and polypyrrole at (1×10−3) M and 0.20 M respectively and change the concentration of p-toluene sulfonate from 0.05 M-0.30 M
The PPy-PEG composite films prepared at various concentrations of PEG ranging from 0.5×10−3 M-9×10−3 M in the aqueous solution containing 0.20 M pyrrole and 0.10 M p-toluene sulfonate at a potential of 1.20 volt has been studied to investigate the effect of PEG concentration on the thermal diffusivity the films
Summary
Study is to investigate the thermal diffusivity as a function of process parameters such as different. Photoacoustic spectroscopy (PAS) found important applications in research and analysis of inorganic, organic and biological solids and semisolid. Concentrations of insulating polymer, monomer and electrolyte and the different applied voltages effects used to prepare PPy-PEG composite film. It is a non-destructive technique that is applicable to almost all types of samples.
