Conducting Core-Shell Poly(Styrene/Pyrrole) Latex Particles Prepared by Fe3+-Catalyzed Oxidative Polymerization during Emulsifier-Free Emulsion Polymerization |
| 초록 |
Core-shell poly(styrene/pyrrole) latex particles were successfully prepared by oxidative polymerization during emulsifier-free emulsion polymerization. We tried to reduce a cost and effort to synthesize the latex particles by using one-step reaction. The core-shell structure of the resulting latex particles was proved by TEM analysis. Synthetic mechanism of core-shell poly(styrene/pyrrole) latex particles was proposed by SEM analysis with the passage of polymerization time. It supported a strong evidence that each composition was isolated in each domain, and which was corroborated by the TGA analysis. The resulting latex particles showed high conductivity after doping and drying. This new strategy is universal for the synthesis of many other conjugated materials or composite particles with controlled morphology. Such morphology controlled conjugated polymer composite particles (i.e., core-shell) may have potential practical applications in various electrical devices and sensors. |
