Rayappan %J Journal of Applied Sciences %D 2012 %I Asian Network for Scientific Information %X The Ag-PANI nanocomposite was prepared using wet chemical synthesis method. The morphological and optical characterization studies were carried out using FE-SEM and UV-Visible spectrophotometer. The FTIR band peaks confirmed the presence of the polyaniline in the Ag-PANI nanocomposites. Variation of the optical characteristics of the Ag-PANI nanocomposites was studied while adding the PVA and acetonitrile. The non linear optical behaviour of Ag-PANI nanocomposite material was studied using the Z-scan measurement technique. %K Nonlinear optics %K thin film %K Ag-PANI nanocomposite %K nanostructure %K nanocomposite %U http://docsdrive.com/pdfs/ansinet/jas/2012/1691-1695.pdf
