Patent number: 10793728Abstract: An improved superhydrophobic coating and a process of making it is provided herein. More particularly, a robust superhydrophobic coating is produced by using carbon dioxide to enhance the integration of a binder material into the superhydrophobic coating. The carbon dioxide may be used to infiltrate and fill the interstitial voids of a superhydrophobic material, such as diatomaceous earth. Consequently, occupying these voids in the superhydrophobic material effectively blocks other components (e.g., binders) from entering the voids. As a result, the coating formulations of the present invention are more robust and may strongly adhere to the substrates to which they are applied.Type: GrantFiled: June 6, 2018Date of Patent: October 6, 2020Assignee: Honeywell Federal Manufacturing & Technologies, LLCInventors: George Bohnert, Jamie Messman
