ResearchMiniemulsions are a special class of emulsion (typically a dispersion of submicroscopic droplets of oil in water), which allow the preparation of materials (polymers, composites, encapsulated particles, etc.) that can not be made by the conventional industrial emulsion techniques. These materials can have applications ranging from the mundane but important (e.g., adhesives and coatings) to the exotic (e.g., biomedical and optoelectronic devices). However, a crucial aspect of the understanding of how these miniemulsions are transformed into the final products has been lacking because of the difficulty in observing such small size species (often in the nanosize range); the usual measurement methods disturb the size of the species simply by the act of trying to measure them. Solutions to this dilemma (some involving recently developed technology) and their application will be explored in the fundamental aspect of this research.The application of miniemulsions to the preparation of new materials will be explored with some emphasis on unique photonic devices. The special ability of miniemulsions to control various properties of the materials (including size, composition, surface properties) will be exploited in this research.Broad ImpactThe fundamental work is expected to have a direct and substantial impact on the ability to apply miniemulsion technology to the development of unique materials both in this work at Lehigh and for others, particularly in industry. As water-based systems, they can promote environmental responsibility in large volume applications such as coatings and adhesives. Small-volume, high-value materials are envisioned in drug delivery, medical diagnostics, and photonics and optoelectronics. The rapid dissemination of the results will be ensured; annual presentations to members companies of the Emulsion Polymers Institute's Industrial Liaison Program, as well as lectures at short courses (Advances in Emulsion Polymerization and Latex Technology; at Lehigh and overseas) designed for industrial research scientists and engineers will include significant findings, in addition to the expected presentations at international meetings and publications in prominent journals.

研究细乳液是一类特殊的乳液（通常是亚微观油滴在水中的分散体），它允许制备材料（聚合物，复合材料，包封颗粒等）。这是常规工业乳液技术所不能制备的。这些材料可以具有从平凡但重要的应用（例如，粘合剂和涂料）到外来的（例如，生物医学和光电器件）。然而，由于难以观察这种小尺寸物质（通常在纳米尺寸范围内），因此缺乏对这些细乳液如何转化为最终产品的理解的一个关键方面;通常的测量方法仅仅通过试图测量它们的行为来干扰物质的尺寸。解决这一难题的方法（有些涉及到最近发展起来的技术）及其应用将在本研究的基础方面进行探索。将探讨细乳液在制备新材料中的应用，重点是独特的光子器件。细乳液的特殊能力，以控制各种性质的材料（包括大小，组合物，表面性能）将被利用在本research.Broad ImpactThe基本工作预计将有直接和实质性的影响的能力，应用细乳液技术开发独特的材料，无论是在这项工作在里海和其他人，特别是在工业。作为水基系统，它们可以在涂料和粘合剂等大批量应用中促进环境责任。小体积，高价值的材料被设想用于药物输送，医疗诊断，光子学和光电子学。将确保结果的快速传播;每年向乳液聚合物研究所工业联络计划的成员公司进行介绍，以及在短期课程中进行讲座乳液聚合和胶乳技术的进展在利哈伊和海外）设计的工业研究科学家和工程师将包括重要的发现，除了预期在国际会议上发表演讲和在著名期刊上发表文章之外。
