Abstract
The invention provides an electrospinning apparatus, which comprises one or more spinneret, a rotating collector disposed from the spinneret and configured to collect the fibers, and a sideway motion device disposed on or connected to the spinneret or the rotating collector and configured to propel or move the spinneret or the rotating collector, wherein the sideway motion device is controlled by a controlling unit for providing an angular speed (θ) of the sideway motion with a formula: θ=tanx/H wherein x is a parallel motion speed of the device and H is a vertical height between the spinneret and the rotating collector and wherein the angular speed (θ) is in a range of about 1.0×10to about 1.0 (°/sec). Also provided is the 2-D or 3-D membranes produced therefrom and a method of using the apparatus of the invention.
