a b s t r a c t This paper presents a method for the preparation of silver nano-particles in poly (diallyldimethylammonium chloride) (PDDA) using N,N-dimethylformamide (DMF) as a medium has been performed successfully. A golden solution in its UV–vis absorption spectrum showed surface plasmon resonance absorption bands between 410 and 425 nm in solutions and at about 461 nm in a transparent film. The Ag/PDDA nano-composite was characterized by X-ray diffraction (XRD) measurement, transmission electron microscopy (TEM), scanning electron microscopy (SEM), Fourier-transform-infrared spectroscopy (FTIR) and thermo-gravimetric analysis (TGA). XRD showed the fcc crystal structure of the bulk Ag with particles of
