Preparation and dielectric properties of polyimide nanocomposite films using polypyrrole-polyimide core-shell nanoparticles |
| 초록 |
In this presentation, we fabricated polyimide nanocomposite film having polypyrrole(PPy)-polyimide(PI) core-shell nanoparticles. PPy nanoparticles were polymerized by various oxidant and surfactant such as ammonium persulfate, iron(Ⅲ) chloride, dodecyltrimethylammonium bromide(DTAB), dodecylbenzensulfonic acid(DBSA), dioctyl sodium sulfosuccinate(AOT) and Triton X-100. To restrict of electron transfer between PPy nanoparticles, we encapsulated sphere PPy by insulating polyimide shell which revealed dielectric property. The structure and shape of PPy and PPy@PI nanoparticles were analyzed by FT-IR and SEM. The dielectric properties of PPy@PI nanocomposite films were studied using impedance analyzer. These nanocompisite films are promising for use in all-polymer nanocomposites for high dielectric materials. |
