One-step Synthesis of Polystyrene/Polythiophene Core/Shell Nanoparticles via Dual Initiation System |
| 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 dual initiation system. The average particle size of the particle was approximately 300 nm and its core-shell morphology was proved by backscattered SEM imaging. 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. |
