Ultrathin metal-organic framework nanosheets prepared via surfactant-assisted method and exhibition of enhanced anticorrosion for composite coatings

As a vital branch of two-dimensional material, organic framework material sparked wide interest, but generally water is a serious threat to its structure. Aiming to obtain organic framework materials with water stability, a bottom-up approach to building porphyrin-paddlewheel metal-organic framework (MOF) nanosheet assisted by surfactant is developed, where the obtained ultrathin nanosheet possesses more uniform scale and higher yield than traditional exfoliation obtained. Then Cu-MOF nanosheets are used as nanofillers into epoxy thermoset and prominently improve the protection properties of coatings compared with the controlled samples and bulk material demonstrated by the electrochemical measurement.

Automated summary

The bottom-up approach to building porphyrin-paddlewheel metal-organic framework nanosheets assisted by surfactant results in materials with more uniform scale and higher yield. Furthermore, the incorporation of Cu-MOF nanosheets as nanofillers into epoxy thermoset significantly enhances the protective properties of coatings.
