Abstract Nanofiber yarns offer unique opportunities for developing next-generation flexible materials that combine nanoscale functionality with macroscopic structural integrity. Their high surface-to-volume ratio, fine open porosity, and fibrous morphology enable applications in tissue engineering, drug delivery, filtration, sensors, energy storage, and functional textiles.

Methods for increasing productivity of AC-electrospinning using weir-electrode - Scientific Reports

|
By Ondrej Batka, Josef Skrivanek, Jaroslav Beran, Pavel Holec, Jan Valtera
| Nature Verified
Abstract The presented work brings new knowledge in the field of spinning electrodes for AC‑electrospinning technology, which is used for producing nanofibrous structures using a solution of polyvinyl butyral. It presents new types of spinning weir‑electrodes and describes research on the influence of electrode design parameters on the stability of the spinning process and the productivity of nanofiber production. The multistage spinning electrode is presented in the ratio of stages one to five.
