Abstract Scope |
Superhydrophobic coatings are well-suited for corrosion prevention thanks to their ability to retain air pockets between the corrosive liquid and the coating, which could greatly reduce the contact area with the corrosive liquid and thus retard corrosion. In this study, a porous surface layer made of nano-raspberry shaped silica nanoparticles was prepared to trap air and induce superhydrophobicity. This porous surface layer produced via layer-by-layer assembly was further optimized by altering the size, deposition sequence, and dispersion medium of silica nanoparticles. By combining the optimized superhydrophobic top layer with a bottom layer based on corrosion inhibitors, a multilayer coating that could significantly improve the corrosion resistance of carbon steel in CO2-saturated water was obtained. |
