| Summary: | 碩士 === 國立高雄應用科技大學 === 化學工程系碩士班 === 92 === The propose of this study is to prepare polyaniline/synthetic mica nanocomposites by intercalating anilinium into pristine synthetic mica followed by the in-situ polymerization of the anilinium within the interlayer gallery. The synthesis and characterization of the polyaniline/synthetic mica intercalated nanocomposites with dangling chains are carried out in this study. The properties of polyaniline/synthetic mica nanocomposites are measured by wide angle X-ray diffraction (WAXD), FT-IR, UV-VIS, conductivity measurement, transmission electron microscopy(TEM), and scanning electron microscopy(SEM). The results illustrate that the conducting polyaniline intercalated into the galleries of the synthetic mica which demonstrating WAXD patterns with lower angles. The red shifting of UV-VIS spectra, the increasing length of conjugation of polyaniline chain were found when intercalation occurs. The degrading rate of polyaniline/synthetic mica nanocomposites at high temperature was greater than that of the bulk polyaniline and the degradation temperature was higher by 37℃. The FT-IR spectra show that a slight shift for the intercalated nanocomposites, due to the formation of hydrogen bonds between hydroxyl group and amine.
