Abstract
Provided is a method of manufacturing fiber with aligned porous structure, an apparatus, and applications of the fiber. The apparatus comprises: a fiber extrusion unit, a freezing unit, and a collection unit for collecting the frozen fibers, wherein fibers extruded from the fiber extrusion unit pass through the freezing unit. Continuous and large scale preparation of such fiber with aligned porous structure is achieved by combining directional freezing and solution spinning.
