Abstract
Systems, apparatuses, and methods for reducing humidity of air adjacent to a nozzle of an electrospinning apparatus, charged solution output by the nozzle, a solution path between the nozzle and a deposit surface, and/or the deposit surface. The apparatus can be configured to controllably output the charged solution and gas of a predetermined dryness for deposit of the charged solution on the deposit surface. The gas of the predetermined dryness can be provided adjacent to a nozzle tip of the nozzle from where the charged solution is output. The gas of the predetermined dryness may be output in a predetermined direction toward a focal point at, in front of, or behind the nozzle tip.
Claims18
An apparatus configured to controllably output a charged solution and gas of a predetermined dryness, the apparatus comprising:
- a nozzle configured to output the charged solution from a nozzle opening at a nozzle tip of the nozzle;
- a gas output port arranged relative to the nozzle configured to output the gas of the predetermined dryness at a predetermined rate at a discharge opening of the gas output port, and in a predetermined direction, such that the gas of the predetermined dryness is provided adjacent to the nozzle opening;
- and
- a controller configured to control the gas of the predetermined dryness output from the gas output port at the predetermined rate such that the gas of the predetermined dryness does not propel flow of the output charged solution or modify shape of the flow of the output charged solution,
- wherein the gas output port is configured to output the gas of the predetermined dryness in the predetermined direction toward a focal point at, in front of, or behind the nozzle opening.
