Abstract
[ $TiO_2/PVP$ ] nanofibers were electrospun by varying the collector grounding design to improve the axial alignment of fibers. The collectors are composed of two pieces of conductive substrates separated by a gap f3r the uniaxial alignment of fibers (X design). The collectors consisting of two sets of substrates placed by $90^{\circ}$ (XY design) equipped with a timer are also prepared for biaxial alignment of fibers. Both collectors show that the charged nanofibers are stretched to span across the gap between the electrodes. Experimental results reveal that the latter collector is more effective on the directionality of electrospun $TiO_2/PVP$ nanofibers due to the dissipation of accumulated electric charge between the collectors.
