The coating includes a partially fluorinated hexafluoropropylene copolymer binder in a nonfluorinated solvent that dissolves the binder and does not dissolve the microparticles. The coating is heated sufficiently to bond the microparticles to the binder but not so much as to cause the receding water contact angle for the coating to fall below 80°.Type: GrantFiled: December 20, 2006Date of Patent: January 21, 2014Assignee: 3M Innovative Properties CompanyInventors: Naiyong Jing, Lisa P.

R1 is an organic group, and each R2 is H or a chemisorbed group, with at least one R2 being a chemisorbed group. The polymer may be a nanostructured film. Also provided herein is a method of: converting a di-p-xylylene paracyclophane dimer to a reactive vapor of monomers; depositing the reactive vapor onto a substrate held at an angle relative to the vapor flux to form nanostructured poly(p-xylylene) film; reacting the film with an agent to form hydrogen atoms that are reactive with a precursor of a chemisorbed group, if the film does not contain the hydrogen atoms; and reacting the hydrogen atoms with the precursor. Also provided herein is a device having a nanostructured polyp-xylylene) film on a pivotable substrate. The film has directional hydrophobic or oleophobic properties and directional adhesive properties.Type: ApplicationFiled: September 5, 2013Publication date: January 9, 2014Applicant: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Walter J.
