Novel graphene-enhanced spray coating enables efficient structural health monitoring in demanding environments

Researchers from China’s Northeastern University, Shenyang Jusheng New Material Technology, Key Laboratory of Medical Image Computing, Shenyang Aerospace University and Australia’s University of New South Wales have developed a polyurea-based nanocomposite spray sensing coating reinforced with covalently functionalized graphene nanoplatelets, offering a scalable solution for structural health monitoring in demanding environments.

Preparation and Main Properties of Graphene NanoPlatelet-functionalized Polyurea Coatings.

Structural health monitoring (SHM) in harsh and complex conditions remains challenging, as conventional sensors often lack conformability, mechanical durability, and long-term stability. In their recent study, the team outlines a new approach – a spray-applied polyurea nanocomposite sensing coating that integrates functionalized graphene nanoplatelets to combine robust mechanical performance with reliable, real-time damage and strain monitoring for infrastructure and automotive structures.
