Abstract
A corrosion detecting composition comprising a nanoparticle and at least one chemically reactive adsorbate associated with the nanoparticle. The chemically reactive adsorbate displays a responsive surface enhanced Raman scattering (SERS) spectral response that is a function of pH. The nanoparticle is contained in a selective carrier; such that the selective carrier allows transport of protons or hydroxide anions to the chemically reactive adsorbate associated with the nanoparticle. Lastly, the selective carrier restricts transport of organic chemical compounds to the at least one chemically reactive adsorbate. This allows the Raman sensor molecules to be blended with paints and coatings prior to application on metal surfaces, and the Raman sensor molecules do not prematurely react with the components of paints or coatings. A Raman detectors can be used to non-destructively interrogate the Raman sensor molecules and detect the pH changes associated with undercoat corrosion.
