Investigation on Optical, Morphological and Thermal Properties of Spray Coated Polypyrrole Film

摘要: Soluble polypyrrole has been synthesized by In-situ chemical oxidative polymerization method in aqueous solution of pyrrole monomer. The contained dodecyl benzene sulfonic acid (DBSA) as a dopant and ammonium persulfate (APS) an oxidant. reaction temperature was 20°C for 24 hours. prepared dissolved m-cresol solvent. coated on glass substrate spray coating technique at 200°C 5 minutes. attachment group is confirmed the structure FTIR spectroscopy. absorption PPy film 360 nm 600 UV emission wavelength found 415nm well direct band gap 2.8eV. XRD study shows crystalline nature DBSA doped film. SEM graph reveals globular morphology presence functional PPY surface. TGA good thermal stability
