In the present century, the combination of conductive polymers, e materials that, in addition to improving the general properties of polymers, also have electrical and magnetic properties, with natural biopolymers for intelligent food packaging has received much attention. In this research, the effect of polypyrrole nanoparticles in the combination of different concentrations chitosan polypyrrole nanocomposite was prepared. The structural and functional properties of the films were investigated. The size, shape and morphology of the synthesized particles were investigated using electron scanning microscopy technique. The results showed that the synthesized polypropols are granular in shape and in the dimensions of 90-100 nm. The antioxidant properties and electrical conductivity of the films were investigated. The results showed that following the synthesis of polypyrrole nanoparticles in the chitosan polymer matrix, the electrical resistance decreased and the electrical conductivity increased. Also, the results of investigating the effect of polypyrrole on the physical properties of chitosan films showed that with increasing the concentration of polypyrrole and the time of synthesis of solubility and water vapor permeability of films decreased. The interaction between chitosan and polypyrrole was confirmed by infrared spectroscopy and X-ray diffraction pattern.
