缓蚀组装技术，提供了按设定方式修饰金属表面的方法，对腐蚀电化学反应具有钝化作用，是自组装技术最具实用化的发展方向之一。建立多层次的可控组装新方法，是缓蚀组装研究的核心问题。三唑类化合物是铜及其合金的特效缓蚀剂，能够在铜表面上形成链状聚合物保护膜。但是目前对其聚合和缓蚀协同规律，尚需进行深入研究。点击化学反应具有模块化、高产率、条件温和等特点，为表面组装注入了新的活力。本课题拟通过Cu(I)催化合成三唑环的点击化学反应，在铜表面制备共价键合的三唑类缓蚀多层膜，寻找有效控制三唑环的聚合度和聚集行为的化学方法。利用光激发和衰减的丰富信息，结合表面分析技术和腐蚀电化学测量方法，研究组装多层膜中三唑环的聚集结构和协同规律，为点击组装体系的在线测量和实时控制提供理论基础，在铜表面构筑有序而且稳定性好的缓蚀膜，这对于多层次缓蚀组装新体系的发展具有重要的理论意义。

The supramolecular assembly technique provides a method to modify the metal surface according to designed modes and has a potential application for metal protection.The self-assembly membrane has less defect for its molecules oriented orderly, showing a suppression effect for corrosion electrochemical reaction. However, the ordered structure is thermodynamic unsteady state.With the time prolonged, the emerging of molecule aggreates give rise to structure turbulence, which leads to the loss of its corrosion protection effect. Establishing the controllable assembly method is the core issue of anti-corrosion self-assembly research. Triazole compounds are effective corrosion inhibitors for copper and its alloys. It still deserves comprehensive studies for the aggregation behaviour and synergistic rule of triazole molecules. Click chemisty reactions have advantages of modular,high yield and moderate reaction conditions.It gives a new vitality for the developement of assembly technology.This project intends to construct covalently bound mulitilayer films on copper surface using click chemistry of Cu(I) catalysized trizaole cycloaddition. The abundant information of light excitation and attenuation was used to elucide the aggregates action and synergism of the inhibitive molecules in the assembly films. The combination with the surface analysis techniques and electrochemical measurements will also adopted.Control methods for the defects in the assembly film will develope to seeking the new principle for preparing inhibitive multilayer films with stable and orderly structure.It has important meanings for promoting the development of the corrosion inhibition assembly techniques.
