Rare earth oxide surfaces


Rare earth oxides (REOs) have been suggested as potential promising materials to overcome the limitation of conventional hydrophobic coatings. REOs are inorganic materials, thermally robust and their cost is low. Despite the unsolved discrepancy on the main cause of hydrophobicity of REOs, REOs can maintain hydrophobicity even after being exposed to various harsh environment.

MEL develops a thin (∼200 nm) nanostructured REO surface on popular engineering materials by utilizing a wet chemical method, in order to achieve the enhanced condensation heat transfer performance with the improved thermal stability.
