Abstract
An electrospinning system, method, and apparatus comprises a dual polarity high voltage power supply with much less power out for safe operation, a solution dispensing assembly held at high positive potential by the dual polarity power supply, a Corona discharge assembly held at high negative potential by the dual polarity power supply, and a drum collector held at ground potential wherein a solution is drawn from the solution dispensing assembly to the drum collector thereby forming a fiber mat.
Claims20
An electrospinning system comprising:
- a power supply;
- a circulation assembly connected to the power supply, the circulation assembly comprising:
- a dispenser;
- at least one spike affixed to a rotating cylinder;
- and
- a conduit configured to allow a solution to flow through the dispenser;
- and
- a collector wherein a solution is drawn from the circulation assembly to the collector via a potential difference between the dispenser and collector, forming a fiber mat on the collector.
