What is it about?

A novel epoxy coating with stable organic radicals cured under a magnetic field exhibits antimicrobial properties. The external magnetic field induces the molecular order and segregation of persistent radicals on the surface of the coating, resulting in the excellent activity against microbes. This antimicrobial action is presumably due to electromagnetism when microorganisms interact with the coating surface.

Why is it important?

This is the first demonstration of an inherently antimicrobial epoxy coating and the first to provide insights on electromagnetism as a probable mechanism for antimicrobial action.


This is the ultimate instalment of my PhD research, and I am very grateful to all my peers for recognising the impact of my work. This work demonstrated that epoxy polymers would exhibit multifunctional character when combined with stable organic radical chemistry. I hope that other researchers will find my work on macroradical epoxies insightful.
