Design and enhanced anticorrosion performance of a ZnMoO·5HO/-BN nanocomposite with labyrinth of nanopores.

Zinc molybdate (ZMO) is a safe and effective grafting material for anticorrosion. Herein, we reported the synthesis of ZMO/-BN with the labyrinth of capillary pores owing to the growth of ZMO on flake hexagonal boron nitride (-BN) using the hydrothermal method. The special morphological structure provided a tortuous path for aggressive species to the steel substrate, which extended and blocked the transmission of aggressive species, enhancing the physical corrosion barrier performance.
