Chemical modification of surfaces

拟议的研究计划侧重于开发化学修饰表面领域的新基础知识。通过开发基于芳香族和脂肪族有机分子氧化和还原的新方法，它将极大地扩展我们目前在表面修饰方面的努力。通过这些互补的改性程序，我们将获得更多具有芳香族和脂肪族接枝基团的改性表面以及伴随的不同性质，并将为几种新的潜在应用开辟道路。这些应用可以在生物传感器、生物材料、化学传感器、分子电子学、电催化、腐蚀保护以及能量转换和存储(例如。燃料电池、太阳能电池、电池和电化学电容器)系统。 该研究计划的长期目标包括通过使用各种前驱体和途径，通过电化学和化学方法开发新的功能化表面。研究计划的具体目标是研究：I-芳香胺和脂肪胺氧化接枝，脂肪族卤化物、烷基和芳香族重氮化合物的还原，以及通过与适当的前体进行双重键合改性；II-所得接枝层的结构、成键和性能；III-概念验证演示这些新材料的潜在应用。

The proposed research program focuses on the development of new basic knowledge in the area of chemically modified surfaces. It will significantly expand our current efforts on modification of surfaces by developing new approaches based on the oxidation and reduction of aromatic and aliphatic organic molecules. With these complementary modification procedures, we will have access to additional sets of modified surfaces having aromatic and aliphatic grafted groups and concomitant different properties and will open the way to several new potential applications. These applications could be in such diverse areas as in biosensors, biomaterials, chemical sensors, molecular electronics, electrocatalysis, corrosion protection and energy conversion and storage (eg. fuel cells, solar cells, batteries and electrochemical capacitors) systems. The long-term objectives of the research program consist in the development of new functionalized surfaces by electrochemical and chemical methods by using various precursors and approaches The specific objectives of the research program are to investigate the: i- grafting by oxidation from aromatic and aliphatic amines, reduction of aliphatic halides, alkyl and aromatic diazonium and modification by dual binding with appropriate precursors; ii- the structure, bonding and properties of the resulting grafted layers and iii- proof-of-concept demonstration of potential applications of these new materials.
