Novel Synthetic Method of Polystyrene/Polythiophene Core/Shell Nanoparticles via Fenton Reaction in Aqueous Medium |
| 초록 |
Polystyrene-polythiophene (PSt-PTh) core-shell nanoparticles were synthesized via surfactant-free emulsion polymerization with oxidative initiation. As a couple agents, hydrogen peroxide (H2O2) and ferric chloride (FeCl3) were used to carry out Fe3+-catalyzed oxidative initiation system. The average particle size of the particle was approximately 300 nm and its core-shell morphology was proved by TEM imaging. In addition, the SEM images supported a clear evidence of distinct core-shell morphology. We proposed a growth mechanism for the formation of the core-shell PSt-PTh particles based on the time-evolution morphology of the particle with SEM images. The result was also corroborated by the time-evolution in situ FT-IR and ξ-potential data. The optical property of core-shell particles was analyzes by Photoluminescence spectroscopy |
