Electrospinning (ES) is a manufacturing technique used for the fabrication of polymer-based nano to microscale fibers with a high surface-area-to-volume ratio. Traditional ES involves a large floor or tabletop apparatus and must include a collection substrate that is electrically charged relative to the spinneret. Here, we report a miniaturized electrospinner designed for efficiency and portability, which eliminates dependency on an electrically connected deposition surface through addition of gas flow. Using the portable system, polyethylene oxide (200k MW) fiber mats were deposited. During ES, air flow rate, separation distance, and applied voltage were varied, and resultant fiber mats were analyzed and compared for quality and dimension. Finite element analysis was used to predict fiber deposition coverage in conjunction with experimental parameters. |
