Abstract: Embodiments described herein relate to articles and methods for forming liquid surface films on the interior surfaces of containers for holding one or more products comprising one or more Bingham plastic materials. Bingham plastic materials behave as a solid under no or low shear stress, and behave as viscous liquids when an applied shear stress exceeds a yield stress. In some embodiments, a container for containing a product includes an interior surface and a liquid disposed on the interior surface. Before introduction of a product into a container, the liquid may be surrounded by air. The liquid-air interface in contact with the interior surface makes a contact angle, θos(a), with respect to the interior surface of the container, of about 0°. After a product has been introduced to the container, the liquid is at least partially covered by the product. The liquid-product interface in contact with the interior surface, makes a contact angle, θos(p), with respect to the interior surface, of less about 60°. The subscript “o” denotes the liquid, subscript “s” denotes the interior surface, subscript “a” denotes air, and subscript “p” denotes a product. In some embodiments, the contact angle θos(p) can be less than about 50°, less than about 40°, or less than about 30°.

Abstract: Embodiments described herein relate generally to devices, systems and methods for producing liquid impregnated surfaces with enhanced durability. In some embodiments, a liquid-impregnated surface includes a first surface having a first roll off angle. A plurality of solid features are disposed on the first surface, such that a plurality of interstitial regions are defined between the plurality of solid features. An impregnating liquid is disposed in the interstitial regions. Furthermore, the interstitial regions are dimension and configured such that that the surface remains impregnated by the impregnating liquid. The impregnating liquid disposed in the interstitial regions defines a second surface which has a second roll off angle less than the first roll off angle. The apparatus also includes a liquid delivery mechanism configured to transfer the impregnating liquid to the interstitial regions.

Abstract translation: 本文所述的实施方案一般涉及用于生产具有增强的耐久性的液体浸渍表面的装置，系统和方法。 在一些实施例中，液体浸渍的表面包括具有第一滚压偏离角的第一表面。 多个实心特征被布置在第一表面上，使得在多个固体特征之间限定多个间隙区域。 浸渍液体设置在间隙区域中。 此外，间隙区域是尺寸和构造，使得表面保持浸渍浸渍液体。 设置在间隙区域中的浸渍液体限定第二表面，该第二表面具有小于第一滚降偏角的第二滚降偏角。 该装置还包括配置成将浸渍液体转移到间隙区域的液体输送机构。
