Fabrications of nanofibers as crossed arrays by electrospinning.
We have developed a new method for obtaining nanofiber crossed arrays by exploiting an auxiliary electrode subjected to electrical frequencies, between the capillary tip and the grounded target in an electrospinning machine. The frequencies generated crossed arrays on a flat collector, used instead of a rotating wheel because of intersecting jets. We observed many straight and crossed structures. We determined the variation in morphology with changes in frequency, and characterized the samples using optical microscopy and a field emission scanning electron microscope. This paper reports on a simple, easy method for generating crossed array nanofibers on a flat substrate using electrical frequency in an auxiliary electrode.
