摘要： A thermoplastic article has a surface with a multiplicity of re-entrant structures extending from the article's surface where a con formal coating comprising a perfluoroalkane covers at least the distal portion of the re-entrant structures to render the article superhydrophobic and oleophobic. A method to prepare the article having a superhydrophobic and oleophobic surface comprises contacting a heated thermoplastic and a mold with voids having at least one dimension of 100 nm to 10 µ?? with a sufficient pressure to cause the thermoplastic to extend into the voids to form features that upon removal of the mold from the thermoplastic article results in re-entrant structures having at least one dimension of 100 nm to 5 µ??. The surface having the re-entrant structures is conformally coated with a compound comprising a perfluoroalkane. Another method to prepare the article having a superhydrophobic and oleophobic surface comprises deposition of microparticlcs or nanoparticles and a resin on a surface of a substrate and curing the resin such that the microparticles or nanoparticles are adhered or mechanically fixed to the substrate with a portion of the microparticles or nanoparticles extending from the surface to form re-entrant structures. The microparticlcs or nanoparticles can comprise a perfluoroalkane or can be conformally coated with a compound comprising a perfluoroalkane, to render the surface superhydrophobic and oleophobic.
摘要翻译：热塑性制品具有从制品表面延伸的多个入口结构的表面，其中包含全氟烷烃的正式涂层至少覆盖入口结构的远端部分，以使制品超疏水和疏油。制备具有超疏水和疏油表面的制品的方法包括使加热的热塑性塑料和模具与至少一个尺寸为100nm至10μΩ的空隙接触具有足够的压力以使热塑性材料延伸到空隙中以形成当从热塑性制品移除模具时导致具有至少一个尺寸为100nm至5μΩ的重新结构的特征。具有入口结构的表面共形地涂覆有包含全氟烷烃的化合物。制备具有超疏水和疏油表面的制品的另一种方法包括将微粒或纳米颗粒和树脂沉积在基材的表面上并固化树脂，使得微粒或纳米颗粒被粘附或机械地固定到基底上，其中一部分微粒或纳米颗粒从表面延伸以形成重结构。微粒或纳米颗粒可以包含全氟烷烃，或者可以共形涂覆包含全氟烷烃的化合物，以使表面超疏水和疏油。

摘要： A thermoplastic article has a surface with a multiplicity of re-entrant structures extending from the article's surface where a con formal coating comprising a perfluoroalkane covers at least the distal portion of the re-entrant structures to render the article superhydrophobic and oleophobic. A method to prepare the article having a superhydrophobic and oleophobic surface comprises contacting a heated thermoplastic and a mold with voids having at least one dimension of 100 nm to 10 μηι with a sufficient pressure to cause the thermoplastic to extend into the voids to form features that upon removal of the mold from the thermoplastic article results in re-entrant structures having at least one dimension of 100 nm to 5 μιη. The surface having the re-entrant structures is conformally coated with a compound comprising a perfluoroalkane. Another method to prepare the article having a superhydrophobic and oleophobic surface comprises deposition of microparticlcs or nanoparticles and a resin on a surface of a substrate and curing the resin such that the microparticles or nanoparticles are adhered or mechanically fixed to the substrate with a portion of the microparticles or nanoparticles extending from the surface to form re-entrant structures.
