NANOSTRUCTURED FRICTION ENHANCEMENT USING FABRICATED MICROSTRUCTURE

摘要

Described herein are fabricated microstructures to adhere in shear to a contact surface. A fabricated microstructure comprises a substrate and a plurality of nano-fibers attached to the substrate. The nano-fibers have an elasticity modulus E, an interfacial energy per unit length of contact w, a length L, a radius R, and are oriented at an angle ?_o relative to the substrate. The length L of the nano-fibers is greater than 0.627?_o R²(E/w)^1/2 with ?_o in radians. Also described herein is a method of forming a fabricated microstructure to adhere in shear to a contact surface and a method of adhering in shear a fabricated microstructure to a contact surface.
