中文摘要
该项目由分析和表面化学计划赞助,继续研究聚合物表面和界面的结构和反应性的测定。这项研究是由Joseph A. Gardella博士和他在纽约州立大学布法罗分校的学生进行的,他们使用x射线光电子能谱(XPS)、飞行时间二次离子质谱(ToF-SIMS)和高分辨率电子能量损失能谱(HREELS)来研究表征良好的大分子体系。这些体系包括单层和多层薄膜、由窄分子量分布的预聚物组成的共聚物体系和结晶度可控的可降解聚合物。该项目阐明了链长、片段分布、小分子量聚合物链的空间分布以及多组分聚合物混合物的分离对表面性能的影响,如附着力、摩擦力和可降解性。该项目产生的信息将对半导体粘合剂、通用粘合剂、润滑剂和低摩擦涂层、生物材料和环保无毒涂层等新材料的设计和开发至关重要。
英文摘要
This project, sponsored by the Analytical and Surface Chemistry Program, continues research into the determination of structure and reactivity at polymer surfaces and interfaces. The research, conducted by Dr. Joseph A. Gardella and his students at SUNY-Buffalo, uses X-ray photoelectron spectroscopy (XPS), time of flight secondary ion mass spectrometry (ToF-SIMS), and high resolution electron energy loss spectroscopy (HREELS) to study well characterized macromolecular systems. The systems include mono-and multi- layer thin films, copolymer systems from narrow molecular weight distribution prepolymers and degradable polymers with controllable crystallinity. The project elucidates the effects of chain length, segment distribution, spatial distribution of smaller molecular weight polymer chains, and segregation of multicomponent polymer mixtures on surface properties such as adhesion, friction , and degradability. The information generated by this project will be extremely important in the design and development of new materials for use as semiconductor adhesives, general use adhesives, lubricants and low friction coatings, biomaterials, and non-toxic coatings for evironmental use.
