Patent ID: 8758668

Claim:
A method for making coiled and buckled electrospun fibers comprising the steps of: (a) providing a solution of a polymer in an organic solvent; (b) feeding the polymer solution of step (a) to a spinneret; (c) providing a collector plate positioned to collect the polymer when the polymer is spun from the spinneret, the spinneret being pointed at the collector plate and the collector plate being positioned at an incline with respect to the direction the spinneret points; (d) subjecting the polymer solution to an electric field such that at least one fiber is electrospun onto said collector plate; (e) relatively moving the inclined collector plate with respect to the spinneret, in a direction transverse to the direction the spinneret points such that, due to the incline of the collector plate, the distance at which the at least one fiber is electrospun in step (d) changes.
