| Summary: | 碩士 === 東海大學 === 化學工程學系 === 96 === Nano-sized core-shell particles were prepared using a mixed surfactant system in a micro-emulsion polymerization process. The core-shell structure that is composed of polypyrrole shell and PMMA core was verified by SEM and FTIR analysis.
Thin films were prepared from these core-shell particles through the thermo-forming. The electric properties of the films were tested with LCR meter in the room condition. Cyclic voltammograms of the film in KCl electrolytes was also obtained for the potential use of the material as super-capacitors. Effects of the preparing processes, PPy fractions, and the concentration of the oxidants were studied. Our results showed a much superior system using the core-shell particles instead of the pure PPy particles.
