ABSTRACT

In order to improve the thermal stability of PAN-based electrospun fibers, AP-PER-MEL and TiO2 were added in to thefibers as additives. The polymer composite with uniformly mixed additional agents was obtained. In case of non-treatedsample, the fibers were burn off completely with high rate within 620oC. But in case of treated samples (EF-M and EF-MT), itis 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 TiO2) into PAN-based electrospun fibers wasconfirmed. Through SEM images, it is confirmed that the fiber shape can be kept even after addition of agents (AP-PER-MELand TiO2). Finally the thermal stability of fibers was largely developed with keeping the nature of PAN-based fibers effectively.
