▎ 摘　　要

A layered double hydroxides (LDHs) nanocontainer film modified with graphene was fabricated on aluminum alloy via a facile two-step process. The structure, morphology and composition of LDHs/graphene film were investigated. Graphene layers were able to seal the pores of nest-like LDHs film. After the modification of graphene, the LDHs film presented hydrophobic (CA 127.8 degrees) and enhanced anticorrosion properties. The active anticorrosion property of the composite film was attributed to the double functions of the impermeable and inert graphene layer and the active inhibitor-loaded LDHs underling film.
