We report on a novel synthetic route for preparing of Silver nanoparticles inside polymer matrix by solid-state chemical reduction of a metallic salt silver nitrate (AgNO3, 99%) under microwave irradiation. The reaction has been performed in an emulsion of copolymers with the presence of ethanol to reduce Ag (I) to the corresponding nanoparticle. The nanoparticle diameters of Ag were found to be from 4 to 12 nm. TEM also indicated uniforms distribution of nanoparticles embedded in the thin film. This approach is more suitable for controlling the nanoparticle size and their homogeneous distribution in the polymer matrix. The effect of Microwave irradiation duration on the reaction rate was investigated by transmission electron microscopy, UV-visible and RX analysis..
