| Résumé : |
DBSA (Dodecylbenzene sulfonic acid)/PSS (Polystyrene sulfonic acid) doped polypyrrole composites were synthesized by in-situ chemical oxidative polymerization method with 0 to 5°C reaction temperature for 24 h. The particle size distribution of DBSA and PSS doped polypyrrole composites were found at 78 nm, 66 nm, 85 nm, 120 nm and 173 nm for different weight ratios of PSS. The presence of sulfur and higher doping level was confirmed by energy dispersive X-ray analysis. The mass percentages of sulfur were found in 17.94%, 34.41%, 40.87%, 44.9% and 48.16% for various weight ratios of PSS. The SEM study shows the granular morphology and aggregation of polypyrrole composites. Thermal stability improves with higher concentration of PSS. FTIR study confirms the presence of dopants in the composite structure. The UV-study reveals the ???* transition in benzenoid rings of DBSA and presence of PSS. The conductivity of polypyrrole composite increases maximum upto 2.5 wt% of PSS and then decreases with increasing PSS content. |
