摘要： Durable superhydrophobic components have a superhydrophobic material disposed (e.g., disposed) thereon that exhibits an apparent advancing dynamic contact angle of ≥ about 150° and a roll-off angle of about ≤ 15° for water after at least 100 abrasion cycles. The superhydrophobic material may comprise a low surface energy material and a polymeric material. The superhydrophobic material may be self-healing and capable of recovering its wettability after damage. In yet other aspects, a component comprises a surface that is superhydrophobic and reduces drag in turbulent flow conditions. The surface has an apparent advancing dynamic contact angle of ≥ about 150° and a roll-off angle of ≤ about 15° for water, and a product of dimensionless roughness (k + ) and a higher-pressure contact angle hysteresis of less than or equal to about 5.8. Methods of making such materials are also provided.

摘要： An anti-icing coating is provided having low interfacial toughness (LIT) with ice. The anti-icing coating includes a polymer and a plasticizing agent. A thickness of the anti-icing coating may be less than or equal to about 100 micrometers (µm). Further, the anti-icing coating has an interfacial toughness (Γ ice ) with ice of less than or equal to about 1 J/m 2 . Such an anti-icing coating may be applied to a substrate or surface of a device on which ice may form, such as aircraft, vehicles, marine vessels, outdoor equipment, snow or ice removal equipment, recreational equipment, wind turbines, telecommunications equipment, power lines, and the like. Methods of forming such anti-icing coatings are also provided.

摘要： Durable icephobic materials form anti-ice coatings on a variety of substrates, including for aircraft, powerlines, vehicles, marine structures, communications towers, outdoor equipment, and the like. The icephobic material may comprise an elastomeric polymer with a low crosslink density (e.g., ≤ 1,300 mol/m3) and low initial ice adhesion strength (e.g., τ ice ≤ 100 kPa prior to exposure to icing conditions). Further, the icephobic material maintains τ ice after 10 icing/deicing cycles that is ≥ 50% of the initial τ ice Introducing optional miscible liquids enhances interfacial slippage of chains in the elastomeric polymer. The low τ ice levels minimize ice buildup and eliminate necessary work to remove any accumulated ice via passive removal during normal operation. Other icephobic materials include linear polymers with plasticizers distributed therein or PDMS-silane coatings, both of which are free of any layers of surface liquids. Methods of making such icephobic materials are also provided.
摘要翻译：耐久的止汗材料在各种基材上形成防冰涂层，包括飞机，电力线，车辆，海洋结构，通讯塔，户外设备等。防冰材料可以包含具有低交联密度（例如，≤1,300mol/ m3）和低初始冰粘附强度（例如暴露于结冰条件之前的τice≤100kPa）的弹性体聚合物。此外，icephobic材料在10次结冰/除冰循环之后保持τice，该结冰/除冰循环≥50％的初始τice引入任选的可混溶液体增强弹性体聚合物中链的界面滑移。低电位水平可以最大限度地减少积雪，并消除在正常运行期间通过被动去除的任何累积的冰来排除必要的工作。其它的防冰材料包括其中分布有增塑剂的线性聚合物或PDMS-硅烷涂层，它们都不含任何表面液体层。还提供了制造这种除臭材料的方法。
