| 摘 要： | 以乳液聚合得到的单分散性聚苯乙烯(PS)微球为种子,利用原位溶胶凝胶技术在微球的表面上吸附上二氧化钛(TiO2)小颗粒,从而得到PS/TiO2复合微球的乳液,利用乳液的自组装得到了PS/TiO2复合材料的蛋白石结构光子晶体。比较了PS蛋白石结构光子晶体和PS/TiO2复合材料蛋白石结构光子晶体的透射谱,得出复合材料的光子晶体带隙特征比PS光子晶体的带隙特征强。

| Abstract: | Monodispersed polystyrene (PS) spheres of different diameter were prepared by emulsion polymerization, and then composite spheres of PS/TiO2 were formed by in-situ Sol-Gel technique, finally photonic crystal of PS/TiO2 opal structure were fabricated by self-assembly. The opal PS colloidal crystals exhibit incomplete photonic band gap, which could be enhanced by replacing the PS spheres with PS/TiO2 composite spheres. |
