Nanofibers

Abstract

We explained the definition of nanofiber and extend the fiber diameter in the nanofiber definition from 1–100 nm to 1–1000 nm because various interesting phenomena are observed between 100 and 1000 nm. We developed the novel electrospinning which is called the blow electrospinning (BES), where we can spin solvent-dissolved polymers. On the basis of BES, we also developed the melt air spinning (MAS), where we can spin molten polymers. Both are categorized into cross air blow spinning (CABS), and their nanofiber productivities are very high so that we can realize the industrialization of nanofibers. The potential applications of the nanofibers by CABS expand to the fields of health and biomedical care, energy and environment, and robot and information technologies.
