Smart Coating for Corrosion Detection and Protection

Looking for a technology to ward off corrosion that’s also safe for the environment? Researchers at NASA’s Kennedy Space Center have done just that. Dating back to the Space Shuttle era of NASA, this technology can prevent corrosion and can also be painted on already-corroded surfaces to “heal” and protect it going forward. With commercial potential in building safer bridges, automobiles and machinery, it’s...

Smart Coating for Corrosion Detection and Protection

Executive summary

The smart coating is based on the controlled release of corrosion inhibitors and indicators from specially formulated microcapsules and particles pioneered by NASA (patent allowed). The coating detects corrosion in its early stages, inhibits it, and/or repairs the coating. The onset of corrosion triggers the release of compounds that indicate and inhibit corrosion. Mechanical damage to the coating triggers the release of film-forming compounds to repair the damage. In practice, the corrosion-responsive microcapsules detect the chemical changes that occur when corrosion begins and respond by releasing their contents. A corrosion indicator will identify the affected region with a color change, and healing agents and corrosion inhibitors help mitigate the corrosion. The microcapsules can be tailored for incorporation into different coating systems. This multifunctional coating system will ...
