Controlled Electrospinning of Fibers

摘要

Electrospinning apparatus and methods for spinning a polymer fiber from a fluid comprising a polymer in the presence of an electric field established between at least one collector and a jet supply device, in a first embodiment comprising: a) forming an electrospinning jet stream of the fluid directed toward the at least one collector; b) controlling dispersion characteristics of the fluid by applying a magnetic field between the jet supply device and the at least one collector; c) forming at least one polymer fiber at the at least one collector; and in a second embodiment comprising: a) forming an electrospinning jet stream of the fluid directed toward a plurality of collectors; b) controlling dispersion characteristics of the fluid by applying different voltages to at least two collectors of the plurality of collectors; c) forming at least one polymer fiber at least one collector of the plurality of collectors.
