1. A method for producing a dry adhesive, the method comprising the steps of:
- providing a spinnable material;
electrospinning the spinnable material to thereby form a non-woven dry adhesive, wherein the non-woven dry adhesive comprises polymeric nanofibers, where said polymeric nanofibers are substantially aligned in a parallel alignment.

Abstract
A method of forming a dry adhesive by includes forming an electrospun non-woven of a spinnable polymer, wherein the polymer fiber forming the non-woven is aligned. A dry adhesive is provided that comprises aligned polymeric nanofibers. The polymeric nanofibers may be formed from a mixture of highly spinnable material is combined with an adhesive component to further enhance the adhesion onto substrates. The non-woven can further be processed by plastic deformation to create microprotrusions.

16. A method for producing a dry adhesive, the method comprising the steps of:
electrospinning a spinnable material to thereby form a non-woven dry adhesive, wherein the non-woven dry adhesive comprises polymeric nanofibers, where said polymeric nanofibers are substantially aligned in a parallel alignment;
the non-woven dry adhesive being capable of adhering to the surface of an adherend, the non-woven dry adhesive thereby being capable of securing the adherend to another surface;
wherein when the non-woven dry adhesive is securing the adherend to another surface, the direction of substantial alignment of the nanofibers is parallel with the surface of the adherend and the surface of the another surface.
