Abstract

Low index magnesium fluoride (MgF₂, n = 1.34) thin film coating is investigated for its hydrophobic property. An effective measure of the hydrophobicity of a surface is the contact angle of a liquid droplet on the surface, which also predicts the surface energy. MgF₂-coated glass is found to have large contact angle as compared to an uncoated glass. MgF₂ thin film coating does not significantly change the optical transmittance property of the glass which makes it a possible hydrophobic coating for windshield application.
