We invented a novel electrospinning setup, which is analogous to a cone-plate rheometer in geometry. The setup allows the shearing of the solution in between the cone and the plate the same way the rheometer does, while with a continuous liquid support system the fibers are continuously emitted and collected in radial direction. We concluded that continuous shearing enhances Taylor-cone formation, which combined with the effect of acceleration, results in finer fibers. The average fiber diameter reduced from 227 to 87 nm because of the rotation. The setup opens new doors on a deeper understanding of the relations of the solution rheology and the fiber forming mechanisms.
