Abstract:
Silver nanoparticles were synthesized by colloidal route using silver nitrate (AgNO3) as precursor and sodium borohydride (NaBH4) as reducing agent. Conducting polymer polyorthotoluidine/silver (POT/Ag) nanocomposites were synthesized by chemical oxidation polymerization in the presence of synthesized silver nanoparticles colloidal solution and the oxidant ammonium peroxydisulfate (APS). The presence of APS has a marked accelerating effect on the oxidation of toluidine with silver nitrate. The nanocomposite was characterized by XRD, FTIR and SEM to study the effect of silver nanoparticles. Oxidations in 1 M HCl acid produced composites in high yield. The XRD image shows a nanoparticular structure of silver which is well dispersed in the polytoluidine matrix. The broadening sharp peaks in the XRD pattern indicate that the synthesized POT/Ag nanocomposite is nanocrystalline. FTIR reveals the presence of silver metal ions uniformly embedded into POT. The molecular structure of the POT-Ag was confirmed by FTIR spectra. SEM reveals the size of nanoparticle and the structure surface morphology of POT-Ag nanocomposite.
