dc.descriptionA new polyimide-silver nanocomposite containing diphenyl sulfone moiety in the main chain was synthesized using a convenient ultraviolet irradiation technique.AgNO3 was used as a source of the silver nanoparticles. Polyimide 3, as a polymer source , was synthesized by the polycondensation reaction of 4,4'-diamino diphenyl sulfone 1 with pyromellitic anhydride 2 in the presence of iso-quinoline as base and m-cresol as solvent. The resulting composite film 3a was characterized by FTIR spectroscopy, Uv-vis analysis, X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetry analysis (TGA) and differential scanning calorimetry (DSC). The X-ray diffraction analysis reveals that silver nanoparticles are present in polyimide matrix. This data is in good agreement with the result obtained from TEM and shows the silver nanoparticles homogeneously dispersed in the polyimide matrix. The UV-vis spectrum shows a single peak at 425 nm, arising from the surface plasmon absorption of the silver nanoparticles.
