This Small Business Innovation Research Phase I project addresses the important problem of replacing anti-corrosion chromate-based pigments in primers for metals. We will mimic the properties of chromate in two novel, on-demand pigments, both added to a primer. The primer will then provide corrosion resistance to several metals such as steel, galvanized steel and aluminum alloys and also protection of defects in the coating due to its slow-release effect. One pigment will consist of an inorganic particle whose surface is a cation exchanger. We will attach corrosion-inhibiting cations to it. The other pigment is an inorganic particle whose surface is an anion exchanger. We will attach corrosion-inhibiting anions to it. When an electrolyte enters the coating, the pigments will release various ions, which are effective in protecting corrosion of aluminum and galvanized steel. When plain water enters the coating, the pigments will remain dormant, i.e., they provide corrosion protection on-demand only. This project will be executed in collaboration with the University of Cincinnati, where more complex ion exchangers will be synthesized and tested.The broader impact/commercial potential of this project is in a new coating technology that is environmentally friendly. The new material will also be flexible, in that we can tailor the four components to a particular metal substrate and primer. As a result, potential customers for this technology will be numerous. Examples are the automotive industry (for car repair finishes, and the painting line in automobile manufacturing plants), wash primers for repair and touch-up, the shipbuilding industry, the aerospace industry (coatings for aircraft), the coil coating (steel) industry, and many others. Combined, these markets represent a commercial opportunity of at least $5 billion. The societal impact will be that workers in paint-manufacturing plants will no longer be exposed to hazardous chromate-containing materials. This project will also enhance our scientific understanding of the mechanisms by which coatings protect metals and how anti-corrosion pigments work in such systems. In particular, the relationship between the hydrophilicity of the coating and the water-solubility of the pigment will be elucidated in this project. The mechanism by which certain inhibitors protect metals is another focus of our study.

这个小型企业创新研究第一阶段项目解决了在金属底漆中替代防腐铬酸盐颜料的重要问题。我们将在两种新型的按需颜料中模拟铬酸盐的性质，两者都添加到底漆中。然后，底漆将提供对几种金属如钢、镀锌钢和铝合金的耐腐蚀性，并且由于其缓释效果，还保护涂层中的缺陷。一种颜料将由表面是阳离子交换剂的无机颗粒组成。我们将在其上附着抑制腐蚀的阳离子。另一种颜料是一种无机颗粒，其表面是一种阴离子交换剂。我们会在其上附着抑制腐蚀的阴离子，当电解质进入涂料时，颜料会释放出各种离子，对铝和镀锌钢的腐蚀有保护作用。当普通水进入涂料时，颜料将保持休眠状态，即，它们仅按需提供腐蚀保护。该项目将与辛辛那提大学合作执行，在那里将合成和测试更复杂的离子交换剂。该项目更广泛的影响/商业潜力在于一种新的环保涂层技术。 新材料也将是灵活的，因为我们可以根据特定的金属基材和底漆定制四种成分。因此，这项技术的潜在客户将是众多的。 例如汽车工业（用于汽车修理面漆和汽车制造厂的涂装线），用于修理和修补的洗涤底漆，造船工业，航空航天工业（飞机涂料），卷材涂料（钢）工业等。 这些市场加在一起代表着至少50亿美元的商业机会。社会影响将是油漆制造厂的工人将不再接触危险的含铬酸盐材料。 该项目还将提高我们对涂料保护金属的机制以及防腐蚀颜料如何在此类系统中工作的科学理解。 特别是，涂层的亲水性和颜料的水溶性之间的关系将在本项目中阐明。 某些抑制剂保护金属的机制是我们研究的另一个重点。
