Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. 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. 2. The coating of claim 1 , wherein the cured nanocomposite film including surface-modified silicon dioxide nanoparticles is prepared from a curable composition comprising an acrylate monomer, silicon dioxide nanoparticles, a silane coupling agent, and a photoinitiator. 3. The coating of claim 2 , wherein 50 weight percent to 80 weight percent of the silicon dioxide nanoparticles have a particle diameter within a range of 20 nanometers to 40 nanometers and 10 weight percent to 50 weight percent of the silicon dioxide nanoparticles have a particle diameter within a range of 70 nanometers to 100 nanometers.
