New Pentafluorothio (SF5) Monomers and Polymers for Fluoro- Enriched Surface Properties

这项研究的重点是使用含SF5的环氧化物和丙烯酸酯作为光聚合合成子来生产耐用的聚合物薄膜和涂料。在小浓度下，合成子将分配到界面，并产生富氟的覆盖层。目标环氧化物和丙烯酸酯将由SF5-碘化物、烯烃、酰基氟化物和醇合成。薄膜的结构将通过X射线光电子能谱(XPS)和红外分析来确定，同时还将测量薄膜的性能，包括折射率、介电常数和表面能。有了这个新的奖项，合成有机计划将支持波特兰州立大学化学系的加里·L·加德博士的研究。加德教授将专注于使用新的和独特的氟化可光聚合合成子来形成新的耐用聚合物薄膜和涂层。氟化薄膜和涂层具有高介电强度、低折射率和良好的环境稳定性。

The focus of this research is the use of SF5-containing epoxides and acrylates as photopolymerizable synthons for the production of durable polymer films and coatings. The synthons, in small concentrations, will partition to interfaces and create fluorine enriched overlayers. Targeted epoxides and acrylates will be synthesized from SF5-iodides, olefins, acylfluorides and alcohols. The structure of the films will be determined by X-ray photoelectron spectroscopy (XPS) and infrared analysis, while film properties, including refractive index, dielectric constant and surface energy will also be measured. With this new award, the Synthetic Organic Program is supporting the research of Dr. Gary L. Gard of the Department of Chemistry at Portland State University. Professor Gard will focus his work on using new and unique fluorinated photopolymerizable synthons to form new durable polymer films and coatings. Fluorinated films and coatings possess high dielectric strength, low refractive index and excellent environmental stability.
