Appl. No.:

12/091855

Inventors:

Naiyong Jing - Woodbury MN, US

Assignee:

3M Innovative Properties Company - Saint Paul MN

International Classification:

B05D 3/02

US Classification:

427375, 524 84, 524167, 524173, 524210, 524356, 524361, 524364, 524365, 524379, 524391, 524520, 524544, 524545, 524546, 525199, 525200

Abstract:

Highly water repellent coated articles may be made by applying to a substrate a coating having dispersed therein or sprinkled thereon partially or fully fluorinated polymer microparticles. 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.

Abstract:

Aspects of the present disclosure are directed to pressure sensing. As may be implemented in accordance with one or more embodiments, an external energy field is applied to a resonant circuit having inductive conductors separated by a compressible dielectric, for wirelessly detecting pressure. Specifically, the resonant circuit is responsive to the energy field and applied pressures by operating in respective states exhibiting different resonant frequencies that are based upon pressure-related compression of the compressible dielectric. These resonant frequencies, or a change in the resonant frequencies, can be used as an indication of the pressure.
