Abstract
Phenolic mercapto oxadiazole and triazole monomers were prepared and then azotized with aniline and Para-phenylene diamine. The prepared monomers have been characterized with FTIR and1HNMR. The six prepared monomers were polymerized by condensation with formaldehyde in a basic medium. The polymer was recognized by FTIR, thermal analysis, and fine elemental analysis (CHN). The results have shown that the presence of azo moiety decreases the thermal stability and the glass transition temperature of the polymers. Also, the oxadiazole polymers are more thermally stable and have higher Tg than the triazole polymers. Doping with different ratios of iodine vapor was carried out on the polymer. The electrical conductivity of the pure and doped polymers was measured by using three probe cells. The results also revealed that the azo moiety increases the conductivity of the pure polymers to some extent (from 1.45534E-11 to 4.69038E-10 ohm-1cm-1 for oxadiazole polymers and from 1.15263E-10 to 3.2680E-10 ohm-1cm-1 for triazole polymers). It was also shown that the electrical conductivity was increased by many orders of magnitude (2-3 orders).by increasing the ratio of the doping.
