When nanotechnology meets filteration: From nanofiber fabrication to biomimetic design

Abstract

Nanotechnology for the scientific and economical revival is of indispensable importance, and the so-called nano-age or nano-industrialization is coming. The paper reveals the very frontier of nanotechnology in mass-production of nanofibers, and the bubble-electrospinning is introduced, and its application to filteration is emphasized. By mimicking the structure of silkworm cocoon, the filteration efficiency reaches its maximum, while the pressure drop through the filter is minimal, and small water cluster is obtained after nanofiber membrane for water purification.
