项目摘要
The main objective of the proposed research is to determine the influence of the electric charge and the composition of electrolyte on the orientation, surface coordination, conformation and the long range order of organic molecules that are adsorbed at metal electrolyte interfaces. Regardless whether monolayers of these molecules, called corrosion inhibitors, or thick layers of protective paints are used, the interaction between the first layer of the film and the metal surface determines the protective functions of these barrier materials. Thus, the focus of the proposed study is on the investigation of behaviour of ultrathin films such as monolayers. Most corrosion inhibitors used today were developed by empirical approach and studied using macroscopic techniques such as impedance analysis that probe only the bulk properties of these materials. The proposed research will complement and enrich existing knowledge on a truly molecular level. Application of a newly developed infrared technique (Polarization Modulation Infrared Reflection Absorption Spectroscopy) will allow us to extract quantitative information regarding orientation of the individual functional groups of molecules in monolayers of protective coatings. The proposed research is important for the protection of the environment and construction materials against corrosion, especially in the petrochemical and power generating industries where corrosion inhibitors are extensively used. It will also provide an understanding of the adhesion properties of protective paint coatings in the automobile and construction industries. Finally, but perhaps most importantly, this work will contribute to the basic research that is aimed at developing a thorough knowledge of the interaction of molecules with interfaces. Such research is pivotal for the further advancement of microelectronics and the emerging field of nanotechnology.
建议的研究的主要目的是确定的电荷和电解质的组合物上的取向,表面配位,构象和吸附在金属电解质界面的有机分子的长程有序的影响。无论使用这些分子的单层(称为腐蚀抑制剂)还是厚层保护漆,薄膜的第一层与金属表面之间的相互作用决定了这些屏障材料的保护功能。因此,拟议的研究的重点是对行为的调查,如单分子膜的薄膜。目前使用的大多数缓蚀剂都是通过经验方法开发的,并使用宏观技术进行研究,如阻抗分析,仅探测这些材料的整体性能。拟议的研究将在真正的分子水平上补充和丰富现有的知识。应用一种新开发的红外技术(偏振调制红外反射吸收光谱)将使我们能够提取定量信息的分子在单层的保护涂层中的各个官能团的取向。建议的研究对于保护环境和建筑材料免受腐蚀,特别是在广泛使用缓蚀剂的石油化工和发电行业具有重要意义。它还将提供在汽车和建筑行业的保护漆涂层的粘附性能的理解。最后,但也许最重要的是,这项工作将有助于基础研究,旨在发展一个彻底的知识分子与界面的相互作用。这种研究对于微电子学的进一步发展和新兴的纳米技术领域至关重要。
