Abstract
Methods for forming a coating can include preparing a nanocomposite film including surface modified silicon dioxide nanoparticles, applying an oxygen plasma treatment to the nanocomposite film to form a treated nanocomposite film, and applying a fluorosilane solution to the treated nanocomposite film to form the coating. A coating can include a nanocomposite film including surface modified silicon dioxide nanoparticles, the nanocomposite film having an oxygen plasma treated surface, and a monolayer of a fluoro alkyl chain.
Claims3
An omniphobic coating, comprising:
- a cured nanocomposite film including surface-modified silicon dioxide nanoparticles, the cured nanocomposite film having an oxygen plasma treated surface;
- and
- a monolayer of a fluoro alkyl chain on the oxygen plasma treated surface of the cured nanocomposite film,
- wherein the omniphobic coating has a contact angle to water of 128 to 138 degrees and a contact angle to oil of 100 to 110 degrees.
