Abstract
En 中文
Here, a new, simple, and effective fabrication method of random and aligned nanofibers by utilizing centrifugal spinning and solution blowing is shown. This process, termed blown-centrifugal spinning (BCS), capitalizes on a rotating reservoir and uses high velocity expanding gas to extrude fibers. The polymer solution is injected from the orifice of the reservoir and is brought in contact with the airflow on the reservoir's surface. The fiber morphology bears a relationship with airflow rate, solution viscosity, surface tension, and solvent evaporation rate. Fiber formation in the flowing stream is controlled by dynamic pressures, surface tension, and viscous forces.
