摘要： A substrate having an undulating surface forming a series of rounded peaks and valleys that produce a continuously curving surface across at least a portion of the substrate. The undulating surface defines a first set of micro features. A second set of micro features molded on the first set of micro features. The substrate is a compression molded polymeric material in which the first and second sets of micro features are formed on the substrate during a single molding step, and wherein the first and second sets of micro features cooperate to increase the surface area and affect at least one of adhesion, friction, hydrophilicity and hydrophobicity of the substrate.

摘要： A microstructure arrangement for gripping low coefficient material comprising: a substrate disposed on a gripping surface; a set of pillars disposed on the substrate; and, wherein the set of pillars have the physical property of a grip force in excess of 50.0N with a contact area of 25% or less as determined by the friction testing method. A first set of pillars can be disposed on the substrate having a cross section area in the range of 100 μm2 to 160,000 μm2, height relative to the substrate in the range of 10 μm to 400 μm, and a pitch determined from the center of the pillars, in the range of 20 μm to 1000 μm; and a secondary set of pillars disposed on the first set of pillars having a cross section area less than that of the pillars in the first set of pillars.

The set of pillars can be on a set of pillars having a cross section area less than that of the pillars. The set of pillars can be defined by pillars each having a cross section width from 0.5 μm to 100 μm and a pitch in the range of 1 μm to 200 μm; and, wherein the set of pillars can be configured to cooperate to have a physical property of a grip force in excess of 50.0 N with a contact area of 25% or less, as determined by the friction testing method.
