Abstract:

Fluoroalkylsilane-treated metal oxide particles and a fluoroelastomeric binder are dispersed in a fluorinated solvent with a low boiling point and applied to a substrate via spray deposition. The spray deposition process rapidly produces a conformal coating that features low surface energy and surface topography with a large range of characteristic length scales and re-entrant curvature, thereby imparting superoleophobicity. The degree of superoleophobicity is readily adjusted by means of altering the ratio of particles to binder. The choice of particle and binder result in coatings with thermal stability for thousands of hours at temperatures up to 200 degrees Celsius as well as desirable mechanical characteristics.

Inventors:

- Berkeley CA, US
Andrew GUENTHNER - Berkeley CA, US

International Classification:

C07D 303/23

Abstract:

Certain embodiments of the invention described herein comprise a composition of matter, and method for preparing the same, which provide the benefits of pre-reaction molecular configuration favoring high liquidity properties, and post-reaction configuration that favors mechanical strength, stiffness, and properties associated with high viscous and/or solid-state materials. In some embodiments, the composition of matter can comprise relaxing photo-isomerizable fragments, of which a fraction can be transformed from trans to cis configurations upon exposure to a photon source. In some embodiments, the composition of matter further comprises thermally reactive fragments, of which can enable thermal solidification of a mixture upon exposure to elevated temperatures. In some embodiments, a composition of matter can be combined with reinforcing additives to form a prepreg combination.

US Classification:

528 55

Abstract:

A method for curing a macromolecular cyanurate network. The method of curing includes suspending a plurality of functionalized silica-coated magnetic nanoparticles in a resin mixture, which includes cyanate ester monomers, cyanate ester oligomers, or both. After a static magnetic field is applied to the plurality of functionalized silica-coated magnetic nanoparticles in the resin mixture, an alternating electromagnetic field (having frequency ranging from about 1 kHz to about 10 MHz) is imposed for a cure time.
