Improvement of Thermal Stability of Electrospun PAN Fibers by Various Additives Lee, Young-Seak; Kim, Min-Il; Im, Ji-Sun; In, Se-Jin;
In order to improve the thermal stability of PAN-based electrospun fibers, AP-PER-MEL and were added in to the fibers as additives. The polymer composite with uniformly mixed additional agents was obtained. In case of non-treated sample, the fibers were burn off completely with high rate within . But in case of treated samples (EF-M and EF-MT), it is sure that the thermal stability was improved by studying TGA data and ISO flammability test about 20 and 30%, respectively. A synergy effect of adding two kinds of agents (AP-PER-MEL and ) into PAN-based electrospun fibers was confirmed. Through SEM images, it is confirmed that the fiber shape can be kept even after addition of agents (AP-PER-MEL and ). Finally the thermal stability of fibers was largely developed with keeping the nature of PAN-based fibers effectively.
