Devices and methods for the production of microfibers and nanofibers having one or more additives

This invention describes how to make tiny fibers, like microfibers and nanofibers, by spinning a liquid material very fast. The material, which is a polymer, also includes a special ingredient called an ionizing compound. The claims narrow this down to using an ionic surfactant, specifically an anionic surfactant, to help create these fibers.

Why it matters: Since 2013, advances in polymer chemistry and the development of novel ionic surfactants have expanded the range of materials that can be effectively spun into high-performance microfibers and nanofibers.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateMotor, rotating spinneret, material feed
