该研究项目在犹他州大学的托马斯毕比教授的实验室中进行，与杜邦中心研究的查尔斯斯图尔特合作，得到了学术联络与工业计划赠款机会下的分析和表面化学计划的支持。 研究了聚四氟乙烯和六氟丙烯溶液沉积共聚物与各种金属和玻璃基材之间形成的界面。 各种光谱探针用于表征聚合物-基底界面，并将其结构和组成与界面粘附力相关联。 X射线光电子能谱将提供有关界面的化学状态信息，TOF-SIMS和扫描探针显微镜将用于表征聚合物的组成和形态。 一个由来自犹他州的科学家和学生以及杜邦公司的科学家组成的合作团队将共同探索这些新颖的技术上有用的系统。新型含氟聚合物-基质界面的光谱学研究正在犹他州大学和杜邦中心研究所的合作研究项目中进行探索。 化学状态信息，聚合物组合物，和表面形态学的研究相结合，给出了一个清晰的画面界面结合在含氟聚合物-金属和含氟聚合物-玻璃系统。 这些新的溶液基含氟聚合物涂层有望在耐腐蚀和低摩擦磨损涂层中获得许多重要的技术应用。

This research project, carried out in the laboratory of Professor Thomas Beebe at the University of Utah, in collaboration with Charles Stewart of DuPont Central Research, is supported by the Analytical and Surface Chemistry Program under the Grant Opportunities for Academic Liaison with Industry program. The research addresses the interface formed between solution deposited copolymers of polytetrafluoroethylene and hexafluoropropylene and various metallic and glass substrates. Various spectroscopic probes are used to characterize the polymer-substrate interface, and to relate its structure and composition to the interfacial adhesion. X-ray photoelectron spectroscopy will provide chemical state information about the interface, and TOF-SIMS and scanning probe microscopy will be used to characterize the polymer composition and morphology. A collaborative team, involving scientists and students from Utah as well as staff scientists at DuPont will work together to explore these novel and technologically useful systems. Spectroscopic studies of novel fluoropolymer-substrate interfaces are being explored in this collaborative research project involving the University of Utah and DuPont Central Research. Chemical state information, polymer composition, and surface morphological studies are combined to give a clear picture of interfacial bonding in fluoropolymer-metal and fluoropolymer- glass systems. These new solution based fluoropolymer coatings promise a number of important technological applications in corrosion resistant and low friction wear coatings.
