This Small Business Innovation Research Phase-I project employs the development of intelligent and sustainable coating technology to present a game changing option to the corrosion protection coating industry. The annual global cost of corrosion is estimated to be US$2.5 trillion while USA alone has to lose more than $1 trillion. The global anticorrosion coating market has been valued for more than US$14 billion in 2015 and is expected to reach beyond US$26 billion in 2022. Apart from inferior performance, currently available corrosion prevention coatings pose significant threat to the environment and human health. It is very hard for the poor and developing countries to bear the related costs. Development of this multifunctional coating will afford them a safer alternative for protecting their assets. In preliminary experiments, this coating innovation has shown significant potential in preventing corrosion and biofouling activity on the treated surface. The thermal analysis and nanomechanical analysis have indicated that these coatings have exceptionally high thermal and mechanical stability approaching that of ceramic materials. Based on the preliminary data, it is safe to state that these coatings present a breakthrough in the area of surface protection through barrier coatings. The intellectual merit of this project includes the development of user friendly multifunctional coating for wide variety of substrates. Historically, chromate conversion coatings (CCC) have been extensively used in preventing metals from corroding. However, there are serious concerns over the use of CCC as it poses human health risks. Carcinogenic hexavalent chromium ions used in coating technology for the corrosion protection of metals are being phased out by Environmental Protection Agency in USA and Registration Evaluation Authorization and Restrictions of Chemicals regulation in Europe. The key innovation of this project is the development of a liquid precursor to a transparent strong ceramic-like coating that can protect substrates from harsh environmental conditions. This ready to use thin coating, suitable for application in the automobile and aerospace industries, adheres strongly to most substrates, adds minimal weight and can be transparent or pigmented. Besides corrosion protection, the coating can also provide scratch resistance, oleophobicity, and possibly anti-microbial properties to numerous surfaces.

这个小型企业创新研究第一阶段项目采用了智能和可持续涂层技术的开发，为防腐涂层行业提供了一个改变游戏规则的选择。据估计，全球每年的腐蚀成本为2.5万亿美元，而仅美国一国的损失就超过1万亿美元。2015年，全球防腐涂料市场估值已超过140亿美元，预计2022年将达到260亿美元以上。除了性能较差外，现有的防腐涂料对环境和人类健康都构成了严重的威胁。贫穷国家和发展中国家很难承担相关成本。这种多功能涂层的开发将为他们提供保护资产的更安全的替代方案。在初步实验中，这一涂层创新在防止处理表面的腐蚀和生物污垢活性方面显示出显著的潜力。热分析和纳米机械分析表明，这些涂层具有非常高的热稳定性和机械稳定性，接近陶瓷材料。根据初步数据，可以肯定地说，这些涂层通过屏障涂层在表面保护领域取得了突破。该项目的智能优点包括为各种基材开发用户友好的多功能涂料。从历史上看，铬酸盐转化膜在防止金属腐蚀方面得到了广泛的应用。然而，人们对CCC的使用表示严重担忧，因为它对人类健康构成风险。用于金属防腐涂层技术的致癌六价铬离子正在被美国环境保护局和欧洲的注册、评估、授权和限制化学品法规淘汰。该项目的关键创新是开发了一种液体前驱体，可以保护基材免受恶劣环境条件的影响，这种涂层是透明的、坚固的陶瓷类涂层。这种即用即用的薄涂层适用于汽车和航空航天工业，对大多数基材有很强的粘附性，增加的重量最小，可以是透明的或有色的。除了防腐外，该涂层还可以为许多表面提供耐刮擦性、憎油性和可能的抗微生物特性。
