Accelerated multistep thermal stabilization of polyacrylonitrile fibers using an ethylenediamine pretreatment

Tunçel, Kemal Şahin; Demirel, Tuba; Karacan, Ismail (Springer, August 202)

The polyacrylonitrile multifilament yarn underwent a multistep heat treatment process including stabilization times ranging from 5 to 75 min following impregnation with a 30% ethylenediamine (EDA) aqueous solution. A series ...
An evaluation of the beneficial effects of polyamide 6's thermal stabilization by ferric chloride complexation as a novel carbon fiber precursor

Demirel, Tuba; Tunçel, Kemal Şahin; Karacan, Ismail (Korean Fiber Society, 2024)

This study investigated the impact of stabilization time on pretreated polyamide 6 (PA6) fibers using various analytical techniques, including thermal analysis (TGA and DSC), infrared (IR) spectroscopy, X-ray diffraction ...
