Proposal Number: CTS-0221809Principal Investigator: Pine, David JInstitution: University of California - Santa BarbaraTitle: Colloidal Engineering of Photonic MaterialsABSTRACTThe PI's propose to study the formation of colloidal arrays within emulsion droplets to template 'supraballs' (which they define as solid spheres containing arrays of colloidal spheres or holes templated by colloidal spheres). Some of the goals include achievement of better control over suprasphere sizes by optimizing a previously developed break-off process and by employing a microfluidic device; understanding of hole/colloid ordering in supraballs and emulsification of colloidal particles; and understanding of optical properties of supraballs (light diffusion). In addition, the PI will attempt to prepare directional colloids within emulsion droplets, intending to assemble these in non close-packed structures which are advantageous for photonic materials.

提案编号：CTS-0221809 首席研究员：Pine, David J 机构：加州大学圣塔芭芭拉分校 标题：光子材料的胶体工程 摘要 PI 建议研究乳液液滴内胶体阵列的形成，以模板“超球”（他们将其定义为包含胶体球阵列或孔的实心球，模板为 胶体球）。其中一些目标包括通过优化先前开发的折断工艺和采用微流体装置来更好地控制超球体尺寸；了解超球中的孔/胶体排序和胶体颗粒的乳化；以及了解超级球的光学特性（光扩散）。此外，PI将尝试在乳液液滴内制备定向胶体，旨在将它们组装成有利于光子材料的非密堆积结构。
