This EAGER project will establish basic knowledge to demonstrate the counter-intuitive notion that certain porous coatings are capable of deterring corrosion. This study will be based on electrochemistry and surface characterization of coated and uncoated metals subject to corrosive environments. The Environmental Chemistry & Technology (EC&T) program team at the University of Wisconsin-Madison will work to establish the links between the type of oxide used in making the coatings, the physical properties of the resulting porous film, and the required corrosion deterring properties. The traditional approach to anti-corrosion focuses on fully covering the surface with a thick layer to avoid the penetration of an electrolyte. This project has the potential to elucidate the role of nanopores on diffusion and reaction and thus to develop understanding of the role of nano-porosity in preventing corrosion.The broader impacts of the project are that it may open up opportunities for new research in the field. Corrosion is a worldwide drain on resources, costing about 3-4% of the economic output of industrialized countries. The nature of this project conveys broad impacts from technological and environmental points of view. These coatings are made from sol-gel chemistries, which are water-based and do not require organic solvents. Since the final products are metal oxides, the coatings are practically inert from a food safety point of view, in addition to having lower VOC emissions than those derived from the application of organic anti-corrosion coatings in a variety of other contexts. Therefore, these coatings may become an environmentally friendly alternative for coating cans and other food-related products and also may have the potential to provide solutions to corrosion problems in a multiplicity of other settings.

这个渴望的项目将建立基本知识，以证明某些多孔涂层能够阻止腐蚀的违反直觉观念。这项研究将基于受腐蚀性环境的涂层和未涂层​​金属的电化学和表面表征。威斯康星大学麦迪逊分校的环境化学与技术（EC＆T）计划团队将努力建立用于制造涂料的氧化物类型，所得多孔膜的物理特性与所需的腐蚀阻尼特性之间的联系。传统的抗腐蚀方法的重点是用厚层完全覆盖表面，以避免电解质的穿透。该项目有可能阐明纳米孔在扩散和反应中的作用，从而发展对纳米孔隙率在防止腐蚀中的作用的理解。该项目的更广泛的影响可能为该领域的新研究打开了机会。 腐蚀是全球资源的流失，损失了工业化国家经济产出的3-4％。该项目的性质从技术和环境的角度传达了广泛的影响。这些涂层由溶胶 - 凝胶化学材料制成，这些化学是水性的，不需要有机溶剂。 由于最终产品是金属氧化物，因此从食品安全的角度来看，涂料实际上是惰性的，除了具有较低的VOC排放量，而不是在其他各种情况下使用有机抗腐蚀涂料衍生出的发射。 因此，这些涂层可能成为涂料罐和其他与食品相关产品的环保替代品，并且也可能有可能在其他各种环境中提供解决腐蚀问题的解决方案。
