Polymer Surface Chemistry: Structure and Reactivity of Surface Segments and Oligomeric Chain Distributions from Model Systems to Novel Polymer Materials

在分析和表面化学项目的支持下，SUNY-Buffalo的Gardella教授和他的同事正在开发分析聚合物表面的方法。这项工作结合了二次离子质谱、x射线光电子能谱和振动能谱，利用电子和光子来表征聚合物表面的结构和组成。这种多技术方法用于检查聚合物在表面的分布，检查聚合物的生物降解机制，并检查聚合物在表面的三级结构。广泛向当地社区宣传，编写科学教育教材是这项工作的一个重要方面。了解“软”高分子材料表面的结构、组成和化学性质是一个具有挑战性的分析问题。加德拉教授和他在纽约州立大学布法罗分校的同事们正在利用表面敏感光谱的组合来应对这一挑战。在这项工作中开发的方法对聚合物表面的表征具有广泛的工业适用性。在这项研究的背景下，正在对布法罗社区进行广泛的教育推广。

AbstractCHE-0616916Gardella/SUNY-BuffaloWith the support of the Analytical and Surface Chemistry Program, Professor Gardella and his coworkers at SUNY-Buffalo are developing methods for the analysis of polymer surfaces. This work combines secondary ion mass spectrometry, X-ray photoelectron spectroscopy, and vibrational spectroscopy using electrons and photons, to characterize the structure and composition of polymer surfaces. This multi-technique approach is used to examine polymer segment distribution at the surface, to examine the mechanism of biodegradation of polymers, and to examine polymer tertiary structure at the surface. Extensive outreach to the local community, and the development of science education materials is an important aspect of this work. Understanding the structure, composition, and chemistry of the surface of "soft" polymer materials is a challenging analytical problem. Professor Gardella and his coworkers at SUNY-Buffalo are attacking this challenge using a combination of surface sensitive spectroscopies. Methodologies developed in this work have broad industrial applicability for the characterization of polymer surfaces. Broad based educational outreach to the Buffalo community is being carried out in the context of this research.
