微膠囊製備及其在電泳顯示之應用

本論文主要探討愛玉果膠及明膠包覆經陽離子界面活性劑改質之異辛酸銅(Copper(II) phthalocyanine, CuPc)，在乳化系統下，以縮合聚合法製備核心/殼層粒子形式之微膠囊。本論文藉由改變陰離子界面活性劑SDS之添加濃度及利用乳化劑與水相間之界面張力，控制微膠囊之粒徑分佈，探討微膠囊之包覆機制。論文中並輔以紅外光譜對陽離子界面活性劑改質後之異辛酸銅進行結構鑑定，以偏光顯微鏡觀測微膠囊表面形貌及粒徑大小。並將微膠囊封裝於自製電泳裝置中，觀察微膠囊在電壓驅動下之顯示能力。

Copper(II) phthalocyanine (CuPc) was modified by cationic surfactants as the core material, and the shell of the capsule was prepared by jelly fig and gelatin. The core-shell microcapsules were synthesized by condensation polymerization method in emulsion system. The particle size of microcapsules was affected by the concentration of SDS and the interface-tension between the emulsion and water phase. The mechanism of encapsulation was also investigated in this thesis. The morphology and particle size of the microcapsules were observed by Optical microscopy. In addition, chemical structure of the cationic surfactants modified CuPc was characterized by Fourier Transform Infrared Spectrometer (FTIR). In this study, the display ability of the microcapsules electrophoretic device was presented as appropriated electric power was applied.
