    • Compositions and methods are disclosed for imparting ultraphobicity to substrates. Ultraphobicity can be exhibited by superhydrophobicity, oleophobicity, or both. In some instances, techniques for imparting ultraphobicity can include the use of particles that are appropriately configured. For instance, the particles can be arranged to form a roughened surface that enhances and/or imparts ultraphobicity. In another instance, the particles can have surfaces that repel at least one of a oil-based liquid and a water-based liquid. For example, the particles can be attached to an ultraphobic- inducing composition (e.g., copolymer) that comprises at least one polyamine segment and a plurality of branch segments. Such particles can be mixed with a binder composition to form a coating or film for imparting the ultraphobic properties. Other embodiments are directed to other techniques that can also aid in imparting ultraphobicity.
    • 公开的组合物和方法用于赋予底物超疏水性。 超疏水性可以通过超疏水性,疏油性或两者都显示出来。 在一些情况下,用于赋予超疏水性的​​技术可以包括使用适当配置的颗粒。 例如,可以将颗粒布置成形成增强和/或赋予超疏水性的​​粗糙表面。 在另一种情况下,颗粒可以具有排斥油基液体和水基液体中的至少一种的表面。 例如,颗粒可以连接到包含至少一个多胺区段和多个分支区段的超疏水诱导组合物(例如,共聚物)。 这样的颗粒可以与粘合剂组合物混合以形成用于赋予超疏水性质的涂层或膜。 其它实施方案涉及也可以有助于赋予超疏水性的​​其它技术。
