Abstract:
1. A method of manufacturing nanofibers by electrically stretching a solution in space, said method comprising: providing an effusing body including a tip part having an elongated flat face, a plurality of effusing holes terminating in openings in an outer surface of the elongated flat face, and two side wall parts extending along both sides of the effusing holes, the side wall parts rising from the tip part such that the distance between the side wall parts increases in a direction away from the tip part, wherein the openings are disposed at given intervals to form a one-dimensional array and the tip part has a width that is larger than a diameter of the openings; supplying the solution to the effusing body; forming and retaining cones of the solution on the elongated flat face of the tip part of the effusing body, wherein the cones of the solution cover the openings; effusing, into the space, the solution from the cones of the solution that are formed and retained on the elongated flat face of the tip part of the effusing body; and applying a given voltage between the effusing body and a charging electrode disposed at a given distance from the effusing body to produce the nanofibers.
