Nano-structure and hydrophobicity co-determined barrier properties of corrosion protective ZnAl-LDH film in atmospheric environment
Source abstract
Abstract
Salt spray is prone to convert superhydrophobic surface from Cassie-Baxter state to Wenzel state, which accelerates the metallic corrosion. Herein, corrosion process of superhydrophobic coatings were investigated by in-situ growth of LDH lamellae with different platelet spacing and modification of stearic acid. The corrosion protection mechanism of the superhydrophobic coating divided into two stages: the well-known air film blocking effect and the hydrophobicity-depended barrier performance, which is a new focus. Through investigating the influences of the nano-structure on corrosion protection via experiments and simulation, a new mechanism on corrosion protection failure of superhydrophobic surfaces in atmospheric environment is proposed.
