Electrospun PAN precursor

Several research efforts have been attempted to prepare the electrospun PAN precursor nanofibers in the form of an aligned nanofiber bundle [50, 98]. The bundle was then tightly wrapped onto a glass rod, so that tension existed in a certain degree during the oxidative stabilization in air. 

In order to optimize and predict the morphology and average fiber diameter of electrospun PAN precursor, design of experiment was employed. Morphology of fibers and distribution of fiber diameter of PAN preeursor were investigated varying concentration and applied voltage [116],...
