Centrifugal Electrospinning Enables the Production of Meshes of Ultrathin Polymer Fibers

Nanomaterials show extraordinary properties and, among them, polymeric nanofibers are of high interest for several applications. Here, the applicability of a high throughput production system is investigated by combining solution-based electrospinning with centrifugal spinning. Ultrathin nanofibers were generated with diameters in the tens of nanometer regime using polyethylene glycol and polylactic acid, and the productivity of the highly interconnected nanofiber nonwoven meshes was orders of magnitude faster compared to that of materials made with traditional electrospinning methods. Such a manufactured layer of nanofibers shows great potential for filter applications, for example.
