Abstract

Abstract: Electrospinning is often used to produce sub-micron size fibers. Most electrospinning applications employ charged needles or nozzles but have low production rates. For higher production rates several needleless systems have been developed. This work reports on a simple unique needleless method that employs charged vertically oriented threaded rods for holding multiple drops to launch many simultaneous jets. Experiments were conducted with a single rod or multiple rods arranged in a linear array. The direction of the launched jets was controlled using a secondary electrode to direct the jets towards the grounded collector. Results show a single rod of about 50 cm in length can produce PVP fibers at a rate of 4.5 g/hr and 200–400 nm size range.

A single 50 cm rod produced 4.5 g/hr PVP fibers at 200–400 nm size range.
