Methods and systems for manufacturing re-entrant structures, such as the structures exhibiting superomniphobic characteristic, in a continuous, well-controlled, high-rate (mass production, volume) manner are disclosed.

Methods and system for mass production, volume manufacturing of re-entrant structures

An object has a superhydrophic, self-cleaning, and icephobic coating includes a substrate and a layer disposed on the substrate, the layer resulting from coating with a formulation having an effective amount of microstructuring microparticles, liquid silane having one or more groups configured to graft to a microstructuring microparticle and at least another group that results in hydrophobicity. The microstructuring microparticles are dispersed in the liquid silane. Another effective amount of synthetic adhesive, selected from thermosetting adhesives, moisture curing adhesives or polymers that form a strong interaction with a surface, is in solution with a solvent. Upon curing, the layer has a contact angle greater than 90&#xb0; and a sliding angle of less than 10&#xb0; and, less than 5% of an area of the layer is removed in a Tape test.

An object has a durable superhydrophic, self-cleaning, and icephobic coating includes a substrate and a layer disposed on the substrate, the layer resulting from coating with a formulation having an effective amount of hierarchical structuring micro/nanoparticles, liquid silane having one or more groups configured to graft to a hierarchical structuring micro/nanoparticle and at least another group that results in hydrophobicity. The hierarchical structuring micro/nanoparticles are dispersed in the liquid silane. Another effective amount of synthetic adhesive, selected from thermosetting binders, moisture curing adhesives or polymers that form a strong interaction with a surface, is in solution with a solvent. Upon curing, the layer has a contact angle greater than 90&#xb0; and a sliding angle of less than 10&#xb0; and, less than 5% of an area of the layer is removed in a Tape test.

Flexible substrates including a polymer selected from a thermoplastic polymer, a thermoset polymer, and/or a polymer blend, and ferroelectric perovskite-type oxide particles dispersed in the polymer, where the ferroelectric perovskite-type oxide has a dielectric constant that varies with applied voltage. The flexible substrates can be used in tunable electronics.
