Abstract:In the present study, we repeatedly used the surface-applied paste electrolyte cell to record the EIS spectra of four coating systems with different barrier properties exposed to different environments. The absence of a liquid electrolyte allows direct recording of the electrolyte-unaltered coating response to environmental stressors. Exposures included humidity between 23 and 95%, temperatures between 10 and 50°C, 720 hours of ISO 9227 neutral salt spray, 1 year in mild continental urban climate, and for comp… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
