AbstractCHE-0449469Chen/MichiganWith the support of the Analytical and Surface Chemistry Program, Professor Chen and his colleagues at the University of Michigan are examining fundamental aspects of polymer adhesion at interfaces. Using non-linear optical methods such as sum frequency generation spectroscopy, interfacial structures and interactions between polymers and model elastomers are evaluated. Correlation between structural information and adhesion tests determine how segregation, alignment, ordering and bonding of molecules at the interface affect the adhesion interface. This information will be useful in the rational design of adhesion promoters and polymer systems with a wide range of applications. This Career award serves as an integrated training ground for multi-disciplinary graduate students and postdocs, and for outreach to middle school and high school science students.Vibrational spectroscopy using sum-frequency generation methods provides high quality structural information about solid interfaces. When combined with adhesion testing, this structural information provides a fundamental understanding of adhesion between polymer materials with wide applicability. Professor Chen and his colleagues at the University of Michigan are studying this important interfacial process with the support of a Career Award from the Analytical and Surface Chemistry Program. This research area is an ideal interdisciplinary training ground and vehicle for outreach to young scientists.

在分析和表面化学项目的支持下，密歇根大学的陈教授和他的同事们正在研究界面处聚合物粘附的基本方面。 使用非线性光学方法，如和频发生光谱，界面结构和聚合物和模型弹性体之间的相互作用进行了评估。 结构信息和粘附测试之间的相关性决定了界面处分子的分离、排列、有序和键合如何影响粘附界面。 这些信息将有助于合理设计具有广泛应用的粘合促进剂和聚合物体系。 该职业奖是多学科研究生和博士后的综合培训基地，也是初中和高中理科学生的拓展基地。使用和频产生方法的振动光谱学提供了有关固体界面的高质量结构信息。 当与附着力测试相结合时，这种结构信息提供了对聚合物材料之间附着力的基本理解，具有广泛的适用性。 陈教授和他在密歇根大学的同事们正在研究这个重要的界面过程的支持下，从分析和表面化学计划的职业奖。 这个研究领域是一个理想的跨学科培训基地和工具，以推广到年轻的科学家。
