Polyacrylonitrile (PAN) is a synethic semicrystalline resin. PAN nanofibers were electrospun from PAN-based answer for the preparation of carbon nanofibers.The polyyacrylonitrile was hot-stretched by electrospinning method at a very high voltage under temperature controlled oven. Optical microscopy and Scanning electron microscopy (SEM) were utilized to describe the morphology of the nanofibers, which showed that carbon nanofibers were scattered well in the composites and were totally wrapped by PAN matrix. PAN application performance will enhance the mechanical properties and the electrical properties.
