Photoinitiated Polymerization with Visible Lasers

这项工作的目标是研究微胶囊中的化学反应以及微胶囊建立的物理屏障。PI的目标是展示微胶囊化在光处理中的优点和缺点。对试剂和中间体从微胶囊到周围环境的运输以及从微胶囊到周围环境的运输进行了基础研究。实验的重点如下：首先，研究将聚苯乙烯和洋葱盐。目标将是封装产生催化剂并使其在胶囊中分解的光反应化合物。建议进行实验，以跟踪试剂从胶囊中逸出或其与胶囊壁的反应。初步实验表明，这将是一个富有成效的课题。不过，随着实验的进行，更多细节将会浮出水面。根据初步结果，该项目将继续进行电子传递实验、确定试剂在胶囊壁上的迁移的实验以及胶囊/胶囊和胶囊/微珠实验。该奖项涉及通过光聚合形成聚合物的新的、环境友好的方法，并与光致抗蚀剂和光纤涂层等重要技术材料有关。

The objective of this work is to study chemical reactions in, and the physical barriers that microcapsules establish. The PI's goal is to demonstrate the advantages and disadvantages of microencapsulation in photoprocesses. Basic studies of the transport of reagents and intermediates from a microcapsule to the surrounding environment and vice versa, are proposed. The experiments will prioritized as follows: Initially the research will polystyrene and onium salts. The objective will be to encapsulate photoreactive compounds that produce catalysts and cause their decomposition in the capsule. Experiments are proposed to follow reagent escape from the capsule or its reaction with the capsule walls. Preliminary experiments suggest this will be a fruitful subject. Though more details will emerge as the experiments proceed. Depending on the initial results, the project shall proceed to the electron transfer experiments, to the experiments to determine migration of reagents across capsular walls and to capsule/capsule and capsule/bead experiments.%%%This award is in the area of novel, environmentally-friendly processes for forming polymers via photopolymerization, and is relevant to technologically important materials such as photoresists and optical-fiber coatings.
