Abstract
A nanofiber membrane is formed on a microfiber membrane. The nanofiber membrane may be electro sprayed directly onto the microfiber membrane and becomes integrated with the microfiber membrane to form a filter. The microfiber membrane provides structural integrity to for the nanofiber membrane, and an additional microfiber membrane may be added to sandwich the nanofiber membrane.
Claims15
A method of forming a nanofiber filter, the method comprising:
- positioning a microfiber filter and counter electrode a desired distance from a microfluidic emitter, the emitter having a triangular tip with an apex;
- providing a polymer to the microfluidic emitter;
- and
- applying a potential between the microfluidic emitter and the microfiber filter to electrospray nanofibers from a Taylor cone formed at the apex of the triangular tip onto the microfiber filter.
