Abstract
A method is provided for forming a modified gel capable of forming a hydrophobic surface on which water has a contact angle of at least 150°. Additionally, a method is provided for forming a hydrophobic coating from the modified gel. In some embodiments, the hydrophobic coating has an extremely high hydrophobicity with a contact angle in excess of 165°, and good substrate adhesion. The method involves bonding a gel with particulate matter. It is believed that the chemical hydrophobicity of the gel is enhanced by the physical roughness of the particulate matter.
