Synthesis of conducting polymers and metal nanoparticles by using ionizing radiation

Conducting polymer polyaniline was synthesized by radiation method from casting films contg. polyvinyl alc. (PVA) blended with aniline hydrochloride. Upon gamma -irradn. the films changed to PVA/polyaniline nanoparticles as shown by the SEM surface morphol. The UV-Visible spectrophotometer measureme...
