Synthesis and Characterzation of Polythiophene Nanoparticle by Fe3+-catalyzed Soap Free Oxidative Polymerization |
| 초록 |
Poly(Thiophene/Thiophene acetate salt) (poly(Th/TA) nanoparticles were prepared by Fe3+ -catalyzed soap free oxidative polymerization and emulsion polymerization. The size of (poly(Th/TA) nano particles has been controlled by various concentration of monomers, i.e., Thiophene, and Thiophene acetate salt (TA-salt). The TA-salt acts as a polymeric stabilizer and film forming matrix in this study. As the amount of monomer increased, the final particle size of poly(Th/TA) nanoparticles also increased. However, the final particle size of poly(Th/TA) nanoparticles decreased with increase of TA-salt concentration. the size reduction induced the enhancement of photoluminescent property and quantum yield, which was calculated from photoluminescence spectra, due to the increase of surface area. Resulting particles were characterized by UV-vis spectroscopy, photoluminescence spectroscopy, scanning electron microscope (SEM) |
