Abstract

A novel and environmentally benign two-step method has been developed to grow 2D magnesium hydroxide (Mg(OH)₂) nanoflakes. Our method relies on the deposition of Mg films by magnetron sputtering, followed by reaction with water vapor, and does not require any catalyst or harsh acid-base conditions. The 2D nanoflake surface morphology with a crystalline hexagonal structure was dominant on the Mg(OH)₂ films. The water contact angle on the film was ∼139° which testified the good hydrophobicity of Mg(OH)₂ films due to the nanoflake surface. The self-cleaning effect of contaminant particles on hydrophobic Mg(OH)₂ films was analyzed. Compared with other preparation methods, this two-step method is more efficient, cleaner, and simpler, which make it suitable for complex or large-area substrate surfaces. In addition, this method can be applied to other metal hydroxides or oxides.
