Advanced centrifugal electrospinning setup

摘要

An advanced centrifugal electrospinning setup is proposed for the fabrication of non-woven textiles from polymer solutions using a pivotal feed unit and stationary collectors of large diameters and different designs: cylindrical collectors or collectors consisting of circularly arranged metal strips. The use of a collector composed of strips enables the production of aligned fibers. The feed reservoir is supplied with easy to handle interchangeable nozzles with the possibility of varing the nozzle-to-collector gap distance. The simultaneous use of four nozzles results in enhancement of the production rate and shortens the time for fabrication of a denser mat with a large surface area and enhanced exploitation properties. The special construction of the reservoir provides for its negligible dead volume.
