STTR Phase I: Superhydrophobic Corrosion Resistant Coatings

这个小企业技术转让（STTR）第一阶段项目将通过在合金上涂覆耐用的超疏水涂层来证明铁和铝合金的耐腐蚀性。金属的腐蚀对工业国家的经济有重大影响。与腐蚀相关的成本每年以数十亿美元计。 超疏水涂层是由疏水化学品和纳米尺寸的颗粒组成的高度防水涂层。将涂层施加到金属表面上以产生纳米纹理化的疏水表面。水的存在在大多数金属腐蚀过程中起着不可或缺的作用，并且纳米织构疏水薄膜防止液态水润湿/粘附到金属表面。除了将超疏水涂层用于金属腐蚀保护之外，还检查了在超疏水涂层下面施加的底漆层的使用。已知待研究的底漆层具有金属粘附性和防腐蚀性能。超疏水涂层的防腐蚀性能将使用电化学技术进行评估。

This Small Business Technology Transfer (STTR) Phase I project will demonstrate improved corrosion resistance of iron and aluminum alloys by coating the alloys with a durable superhydrophobic coating. The corrosion of metal has a major effect on the economy of industrial nations. The costs associated with corrosion are in the billions of dollars annually. The superhydrophobic coating is a highly water repellent coating that is composed of hydrophobic chemicals and nano-sized particles. The coating is applied onto the metal surface to create a hydrophobic surface that is nanotextured. The presence of water plays an integral role in most metal corrosion processes and the nanotextured hydrophobic thin film prevents liquid water from wetting/adhering to the metal surface. In addition to the use of the superhydrophobic coating for metal corrosion protection, the use of a primer layer that is applied underneath the superhydrophobic coating is examined. The primer layers to be investigated are known to have metal adhesion and anti-corrosion properties. The anti-corrosion properties of the superhydrophobic coatings will be evaluated using electrochemical techniques.
