    • Hydrophobic thermal insulation fiberglass flexible blanket using a textile grade fiberglass is produced by impregnating a hydrophobic polymer (e.g. a fluoropolymer) dispersion into a fiberglass blanket/mat, such as a needle felted fiberglass (FG) blanket/mat. The preferred FG needle felt blanket is a mechanically, rather than organically, bound glass fiber insulating blanket. The hydrophobic polymer dispersion forms a hydrophobic coating on the surface of the fiberglass filaments. Integral hydrophobicity is achieved and maintained without the need to add commonly-used hydrophobic inorganic particles, such as treated silica aerogels or fumed silica. Optionally, to enhance overall hydrophobicity and to inhibit fibrous surface lofting, a super-hydrophobic coating of fluoropolymer and inorganic particles such as silica particles may be dispersed onto one or more surfaces of the blanket. The resulting blanket thermally insulates better than mineral wool; it is equal in insulating properties to (or is slightly better than) untreated FG mat; and it slightly less insulating than aerogel-based blanket materials. It is relatively inexpensive to manufacture, it is flexible, it is durable, it can optionally be made moldable, it eliminates dust, and it remains hydrophobic after long-term heating to 600°F (315°C), or after short-term excursions to temperatures as high as 700 °F (370 °C).
    • 通过将疏水性聚合物(例如含氟聚合物)分散体浸渍到玻璃纤维毯/垫(例如针刺粘合玻璃纤维(FG)覆盖物/垫)中来制备使用纺织品级玻璃纤维的疏水性绝热玻璃纤维柔性毯, 垫。 优选的FG针毡毛毯是机械而不是有机结合的玻璃纤维绝热毯。 疏水聚合物分散体在玻璃纤维长丝的表面上形成疏水涂层。 不需要添加通常使用的疏水性无机颗粒,例如经处理的二氧化硅气凝胶或气相二氧化硅,实现并保持了整体疏水性。 任选地,为了增强整体疏水性并抑制纤维表面放样,含氟聚合物的超疏水涂层和无机颗粒如二氧化硅颗粒可以分散到橡皮布的一个或多个表面上。 由此产生的毯子比矿棉更好地绝热; 与未经处理的FG垫相比,其绝缘性能相等(或略好); 它比气凝胶基材料的绝缘性稍差。 它制造成本相对低廉,柔韧性好,耐用,可以选择性地制模,可以消除灰尘,并且在长期加热到600°F(315℃)或短期后 游览温度高达700°F(370℃)。

    • Compositions and articles comprising omniphobic materials for bio-related and other applications are generally provided. In some embodiments, the compositions and articles described herein may be introduced internally of a subject (e.g., in the esophagus, in the gastrointestinal tract, in the rectum). In some aspects, the compositions and articles comprise a releasable therapeutic agent In some embodiments, the compositions and articles described herein may be configured to have a relatively short retention time at the location internal of the subject (e.g., less than 2 seconds) such as a capsule comprising an omniphobic coating. In alternative embodiments, the compositions and articles described herein may be configured to have relative long retention times at the location internal of the subject (e.g., greater than 10 minutes) and include a mucoadhesive portion as well as an omniphobic portion. Such articles may have an omniphobic portion which resists adhesion and/or fouling (e.g., by foodstuffs and/or other materials present internal of the subject) of the article, such that the mucoadhesive portion maintains adhesion to the location internal of the subject for relatively long retention times. In some such embodiments, the article may be a Janus-type device.
