New smart pipeline coatings

Chemical waste has made it possible to design smart coatings for pipeline. The importance of this innovation consists in the fact that it offers a wide choice of means of protection of conduits of liquid materials. From Max Mann’s explanation, it becomes possible to prevent pipe damage caused by solvents and corrosion.

Max, project manager at Flinders University, also confirms that the repair is simple. Just heat the damaged parts. This smart coating is multifunctional. It therefore leaves room for maneuver during its use.

From refinery-derived chemicals oil have been transformed into a protective coating. These can thus prevent pipe leaks caused by acid. The advantage of this solution lies in its particularly low cost price.

What are the components of this smart coating?

The researchers used sulfur and dicyclopentadiene to create this famous coating. DCPD, a by-product of petroleum refining, helped shape this multifunctional coating. This research result also extended the application of basic chemistry in practical life. Using this new method, the team was able to prevent runaway reactions. The process thus takes place at low temperature, according to Dr. Bowen Zhang, a researcher at the University of Liverpool.

Besides the ability to protect pipes against corrosion, solvents, water and acids, this coating has other advantages. For example, it is able to capture toxic metals such as mercury, etc.

“The Smart Coating’s unique chemistry helps protect substrates, actively removes toxic mercury species from water and oil, and is repairable, ensuring its durability. »

How to repair this smart coating?

Scratches and damage on this smart coating are repairable. The team from Flinders University and Liverpool have revealed that a simple application of heat solves cracking problems. At high temperature, sulfur-sulfur bonds are broken and the chemical structure of the coating changes to rectify any defects.

The collaboration between the Chalker Lab and the Hasell Lab in Liverpool made this research possible. According to J. Chalker, professor of chemistry, this result is a significant advance in the field of multifunctional coating.
