Polyaniline-silver composites prepared by the oxidation of aniline with silver nitrate in solutions sulfonic acids

Popis výsledku v původním jazyce

Aniline was oxidized with silver nitrate in aqueous solutions of sulfonic acids: camphorsulfonic, methanesulfonic, sulfamic, or toluenesulfonic acids. Polyaniline-silver composites were produced slowly in 4 weeks in good yield, except for the reaction, which took place in sulfamic acid solution, where the yield was low. Polyaniline in the emeraldine form was identified with UV-visible, FTIR, and Raman spectra. Thermogravimetric analysis was used to determine the silver content, which was close to the theoretical prediction of 68.9 wt.%. Transmission electron microscopy demonstrated the presence of silver nanoparticles of ca 50nm average sizes as the dominating species, and hairy polyaniline nanorods having diameter 150-250nm accompanied them. The highest conductivity of 880 ScmMINUS SIGN 1 was found with the composite prepared in methanesulfonic acid solution. Its conductivity decreased with temperature increasing in the 70-315K range, which is typical of metals such as silver. The con
