에멀젼중합법으로 제조된 폴리아닐린과 폴리스타이렌과의 전도성블렌드에 대한 연구
The research of one-step emulsion polymerization of aniline and its conducting blends with polystyrene
초록
Stable polyaniline-dodecylbenzenesulfonic acid (PANI-DBSA) fully dissolved in toluene was obtained by a direct one-step emulsion polymerization technique. The polymerization of aniline was carried out in an emulsion comprising water, toluene and DBSA acting both as a surfactant and a dopant for PANI. After the proper washing process was performed, the conductivities of obtained PANI-DBSA complexes increased with increase APS/Aniline molar ratio and DBSA/Aniline molar ratio. The UV-Vis absorption spectra and TGA thermograms of PANI-DBSA complexes also supported these results. PANI-DBSA/PS blends were prepared by mixing PANI-DBSA complexes with PS in toluene. These blends exhibited electrical conductivity of 0.371S/cm at a low PANI-DBSA content (7 wt.%)
