Terminal SF5/Bulky Perfluorinated (Rf)Groups - Formation of Thin Perfluorinated Films

这一项目的主要目标是合成含有各种全氟基团的有机分子，包括五氟氧基和全氟烷基。新的和独特的氟化光聚合合成物将用于形成耐用的聚合物薄膜和涂层，其中氟化成分分配到初始膜的表面。这有可能产生聚合物薄膜，其中富氟覆盖层被纳入其他常规聚合物中。制备完成后，将通过光电子能谱和红外分析确定系统的结构-性质关系；折射率、介电常数和表面能也将被测量。有了这个奖项，有机和大分子化学项目继续支持俄勒冈州波特兰市波特兰州立大学Gary L. Gard教授的研究。加德教授研究了含氟塑料性能的变化，因为塑料的组成部分本身是多种多样的。加德教授实验室正在研究的氟化化合物已经找到了各种应用，如聚合物的溶剂、全氟血液替代品、表面活性剂以及热稳定性和化学稳定性的单体和聚合物。

This project has as its primary aim the synthesis of organic molecules that incorporate a variety of perfluorinated groups, including pentafluorothio and perfluoroalkyl. New and unique fluorinated photopolymerizable synthons will be used to form durable polymer films and coatings in which the fluorinated components partition to the surface of the incipient film. This has the potential to produce polymer films in which a fluorine-enriched overlayer is incorporated into an otherwise conventional polymer. Once prepared, systematic structure - property relationships will be determined by photoelectron spectroscopy and infrared analysis; and refractive index, dielectric constant and surface energies will also be measured.With this Award, the Organic and Macromolecular Chemistry Program continues support for the research of Professor Gary L. Gard of Portland State University, Portland, Oregon. Professor Gard studies the variations in properties of fluorinated plastics as that plastic's constituent building blocks are themselves varied. Fluorinated compounds such as those being investigated in Professor Gard's laboratory have found various applications such as solvents for polymers, perfluorinated blood substitutes, surface active agents, and as thermally and chemically stable monomers and polymers.
