We have prepared nanocomposite films (100-200 nm) of Teflon AF containing Au nanoparticles by using vapor phase co - deposition technique in high vacuum deposition system. Au cluster size, shape and distribution in Teflon AF matrix have been investigated using TEM analysis. XPS and FTIR are also applied to study the chemical composition and structure of the composite. The metal filling factor in the polymer matrix has been estimated by SEM/EDX measurement. The optical properties of Teflon AF/Au prepared at different substrate temperatures of 80 ^o C to 250 ^o C and various metal filling factors have been studied by UV-Visible spectroscopy. Similarly, the variation of electrical properties of Teflon AF/Au nanocomposite at various metal filling factors near the percolation threshold are reported.
