Facile fabrication of electrospun fluorescent graphene nanofiber layer in epoxy coating towards efficient corrosion degree evaluation
Electrospun fluorescent graphene/polyacrylonitrile (R-AMG/PAN)(R-AMG was prepared by acid-modified graphene loaded with rare earth complexes.) and fluorescent graphite/chitosan/polyacrylonitrile (R-AMG/CS/PAN) membranes were incorporated into epoxy resin to develop a smart coating with fluorescence responsiveness to chloride ions (Cl − ), and a comprehensive comparison of both coatings was conducted to assess their ability for corrosion protection and early corrosion monitoring during salt spray testing. Fluorescent graphene is a source for detecting the corrosion behavior of coatings. The use of electrostatic spinning technology significantly enhances the fluorescent properties of graphene. Additionally, the fiber structure enhances the barrier properties of the coating. The work provides a meaningful strategy for the design of intelligent protective materials.
