Abstract
The invention provides a highly aligned and closely packed hollow fiber assembly, wherein the assemblies of fibrous membrane has a width-to-fiber diameter ratio (W/d) larger than 10 and the orientation of the fibers is no larger than +/−10°. Also provided is an electrospinning process for the preparation of the fiber assembly of the invention and its applications.
