Abstract
This application present structures having surfaces with several multivariate and single property engineering applications that are associated with the surface and may be altered by the surface texture or tunable asperities themselves. Depending on the objective of the application, the tunable asperities address the energy requirement for an objective such as gripping or smooth-movement, as well as describes the critical conditions when slippage cannot be prevented. The use in several other energy intensive applications is also discussed as well as for solar, communication altering and color/hue manipulation objectives.
Claims16
An engineered surface that has a texture with at least one asperity arranged in a manner such that the engineered surface is described by an autocorrelation length feature β and RMS R height wherein a ratio of R/β is between 0.001 and 1000 and wherein the engineered surface is designed for up or down wear depending on a rate of change and sign of the rate of change of mean roughness and the autocorrelation length feature β that are engineered with different tip densities of the at least one asperity at different heights from a mean plane.
An engineered surface that has a texture with compositionally varying asperities arranged in a manner such that the engineered surface is described by an autocorrelation length feature β and RMS R height wherein a ratio of R/β is between 0.001 and 1000 wherein the engineered surface has a mean roughness of 100 nm or less and the autocorrelation length feature β is variable between 1 nm and 1 mm.
An engineered surface that has a texture with at least one asperity arranged in a manner such that the engineered surface is described by an autocorrelation length feature β and RMS R height wherein a ratio of R/β is between 0.001 and 1000, and wherein the at least one asperity is comprised of fibril bunching or spreading.
