本論文係有關兼具光、電、磁特性之金屬(Ni，Ag)奈米殼層被覆之聚苯乙烯微球的製備，以形成可藉磁性操控產生單向導電與偏光的材料。
本研究以無乳化聚合法合成聚苯乙烯高分子微球，並於乙二醇系統中進行金屬被覆，製得粒徑均一且分散良好之PS@Ni及PS@Ni@Ag高分子微球。所得PS@Ni@Ag高分子微球平均直徑為287.9nm，根據質量守恆定理及熱重分析與原子吸收光譜分析的估算，Ni與Ag殼層平均厚度分別為0.725與2.5nm。又其紫外光-可見光光譜在452nm處呈現銀之特性吸收峰，且磁性分析顯示所得之金屬(Ni，Ag)奈米殼層被覆之高分子微球因Ni殼層極薄而呈超順磁性。 其飽和磁化量(Ms)、殘留磁化量(Mr)與矯頑磁力(Hc)分別為9.53 emu/g、0.11 emu/g與7.7 Oe。XRD圖譜確認Ni與Ag殼層皆為面心立方體，且氧化鎳在600 oC陳化後形成。
將PS@Ni@Ag高分子微球掺入壓克力膠中製成奈米複合膜，在無外加磁場時，所得複合膜在可見光至近紅外光範圍有吸收，但無偏光特性。在外加磁場進行磁自組所得的奈米複合膜，明顯具有偏光特性，且複合膜中粒子濃度愈高，偏極化的情況愈明顯。

This thesis concerns the preparation of the metal(Ni, Ag) nanoshell-coated polystyrene(PS) microspheres, with some useful properties, like optic, magnetic and electrics, and form material with electric conduction and polarization by magnetic self-assembly.
In this study, polystyrene microspheres were produced by emulsifier-free polymerization and metal coating was performed by polyol process to yield the monodispersed PS@Ni and PS@Ni@Ag microspheres. The average diameter of metal(Ni, Ag) nanoshell-coated polystyrene microspheres was 287.9 nm, and the average thicknesses of nickel and silver nanoshells were estimated to be about 0.725 nm and 2.5nm according to the mass balance calculation and TGA, AA investigation. The special absorption peak of UV-VIS spectra was seen at 452nm, and the magnetic measurements showed the metal(Ni, Ag) nanoshell-coated polymer microspheres were superparamagnetic due to the extremely thin nickel shells. The saturation magnetization (Ms), remanent magnetization (Mr), and coercivity (Hc) were 9.53 emu/g, 0.11 emu/g, and 7.7 Oe, respectively. XRD pattern confirmed the fabricated nanoshells were pure face-centered cubic nickel and silver, and nickel oxides were formed after 600oC annealing.
We also prepared the nanocomposites comprising of cyanoacrylate adhesive and PS@Ni@Ag for using in optics. In the absence of magnetic field, the resultant nanocomposites exhibited an absorption range from UV to NIR region without polarization. After arranging by magnetic self-assembly, the resultant nanocomposites underwent polarization significantly. On increasing the concentration of PS@Ni@Ag, the degree of polarization was larger.
