CAREER: Developing SFG into a Powerful Ananlytical Technique to Unerstand Molecular Adhension Mechanisms at Polymer Interfaces

在分析和表面化学项目的支持下，Chen教授和他在密歇根大学的同事们正在研究聚合物在界面上粘附的基本方面。利用和频产生谱等非线性光学方法，对聚合物和模型弹性体的界面结构和相互作用进行了评价。结构信息与粘附测试之间的相关性决定了界面上分子的偏析、排列、有序和成键如何影响粘附界面。这些信息将有助于粘结促进剂和聚合物体系的合理设计，具有广泛的应用前景。该职业奖为多学科研究生和博士后提供综合培训，并为初中和高中理科学生提供推广服务。使用和频率生成方法的振动光谱学提供了关于固体界面的高质量结构信息。当与粘合测试相结合时，这种结构信息提供了对具有广泛适用性的聚合物材料之间粘合的基本理解。Chen教授和他在密歇根大学的同事们在分析和表面化学项目的职业奖的支持下，正在研究这一重要的界面过程。这个研究领域是一个理想的跨学科的训练场地和工具，以扩大青年科学家。

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.
