Silica nanocontainers with rhodamine B acylhydrazone for early fluorescent detection of steel corrosion.

ABSTRACT: Developing new materials for efficient fluorescent detection of metal corrosion is a highly relevant task. One challenge is that highly sensitive sensors might lose functionality after exposure to certain coating formulations. In this work, silica nanocontainers are used to encapsulate rhodamine B acylhydrazone, an efficient pH sensor. The resulting nanomaterial is then used in water-based epoxy and acrylic coatings for early-stage detection of steel corrosion. Coatings with as little as 0.01 wt% rhodamine B acylhydrazone show a marked increase in fluorescence intensity that correlates with the onset of steel corrosion. Coatings containing the dye encapsulated in silica nanocontainers demonstrate a significantly stronger response (4 times) compared to coatings containing the dye without an
