| Research Abstract |
Electrospinning has been attracting much attention in various fields regarding nanotechnology, in which the nanofibers with highly oriented inner structure, ultimately the extended-chain crystal (ECC), are required to achieve the best performance of mechanical and physical properties. In this study, a novel stretching technique is proposed and applied to polyethylene (PE), and the resultant fiber structure was investigated. In the technique, an electrostatic stretching-force, created by a parallel-electrode collector system, acts on the wet fibers. First, we developed an appropriate spinning system, which enables to make spinning from high-temperature solution stably and to control the evaporation rate of solvent by controlling the environmental temperature. Electron diffraction analysis revealed the formation of highly oriented fiber structure, which is considered to be composed of the ECC mainly. In addition, we have studied the formation mechanism of such highly oriented structure.
