DRY ADHESIVES AND METHODS FOR MAKING DRY ADHESIVES

摘要

Dry adhesives and methods for forming dry adhesives. A method of forming a dry adhesive structure on a backing material, comprises: forming a template backing layer of energy sensitive material on the backing material; forming a template layer of energy sensitive material on the template backing layer; exposing the template layer to a predetermined pattern of energy; removing a portion of the template layer related to the predetermined pattern of energy, and leaving a template structure formed from energy sensitive material and connected to the substrate via the template backing layer.

1. A method of forming a negative mold product having polymer micro- and/or nano-fiber arrays, comprising the steps performed in the following sequence:
providing a template structure formed from energy sensitive material product having fiber arrays selected from the group consisting of (i) polymer micro-scale fibers, (ii) polymer nano-scale fibers, and (iii) polymer micro- and nanoscale fibers; depositing a mold material into the template structure, wherein the mold material is different from a material of the template structure; allowing the mold material to cure; and separating the mold material from the template structure to form the negative mold product having polymer micro- and nano-fiber arrays.
