The Study On The Conductivity Of Polyanline Doped By Nano Particles Instu Prepared By Pulsed Laser Ablation

This paper content two part:the study on the morphology of silica modified with polymer was continualy prepared by pulsed laser ablation. And the coducty of polyaniline doped with instu decorating nano-silica,nano graphite,nano platinum.Liner like and flower like nano silica decorating with polyacrylic acid was continuay prepared by pulsed laser ablation, analysis the possible reasons for the formation of various morphologies. Examining the different modifier concentration, standing time on the morphology of silica.results showed that:a higher concentration of nano particles and modifier in favor of nano assembly out flower like morphology.nano silica,nano graphite,nano platinum which decorating by polyaniline were continued prepared by pulsed laser ablation. the hybrid films were formed of polyamine and these nano particles. hybrid film was characterized by four probe stander conductivity test,TEM,UV-vis,FTIR.TG,XRD,XPS.discussing the thermal and conductivity of hybrid films was affect by different content of nano-silica.Get the conclusion that:nano particles prepared by laser ablation have a small size,not aggregating, and well disperseing in the hybrid.there is strong interaction between nano-particles and polyaniline, nanosilica have destroyed the order of polyaniline molecular chain and decreased the concentration and the mobility rate of carrier.Decreasing the conductivity.while nano graphite and nano platinum increased the electron delocalization of polyaniline,thermal stability and crystallinity, get a better conductivity...
