摘要

Conventional electrospinning (1) permits to obtain micro- and nanofibers that are randomly deposited. Applications that use these fibers, such as filtration, texturing, composite reinforcement, tissue and sensor engineering, could be improved if the fibers could be oriented/aligned (2, 3). Several modifications of the typical electrospinning setup have been considered (3-5) aiming at obtaining: aligned fibers, control of the area covered by the deposited fibers, mixing of fibers of different materials, high production of fibers, definition of fiber patterns, coaxial fibers, smooth fibers and single fibers made of two different materials. These configurations employ additional electrodes, rotating mechanisms and/or multiple capillary for solution injection. Thus, they represent the use of more complicated setups.
