Outline of Final Research Achievements

Fiber-forming source in the melt-electrospinning process is a Taylor-cone which is formed on the melt surface in the presence of high voltage. In this study, we were trying to clarify the fine fiber formation mechanism from the Taylor-cone by using a laser melt-electrospinning system equipped with the scan-type CO2 laser beam melting device.
Using the system, nanofibers were produced form various polymer blend materials. Furthermore, morphologies of the melt-electrospun fibers were investigated. The following conclusions are obtained: 1. inside structure of the Taylor-cone is affected on the diameter of melt-electrospun fibers. 2. diameter of the melt-electrospun fibers decreases with increasing temperature of spinning space.
