Nanocatalyst-mediated oxygen depletion in epoxy coating for active corrosion protection

Smart coatings depending on external nanocontainers are often complex and expensive, which can only inhibit local corrosion depending on the microenvironment change after corrosion. In this work, nanocatalytic anticorrosion based on silica coated nitrogen enriched hollow carbon spheres ([email protected]2) is developed to achieve the prolongation of coating lifetime and long-term protection of metals.
