Abstract

In the PAN-based ACF manufacturing system stabilization step was improved with chemical treatment (preoxidation) in order to yield higher carbon content and to avoid excessive fragmentation during carbonization and activation process. The optimal condition of preoxidation was at 18$0^{\circ}C$ for 4 minutes in sodium glyceroxide in glycerine (concentration of NaOH was 0.02 meq/g). To investigate low temperature stabilization effect, preoxidized PAN fiber heated 22$0^{\circ}C$ to 26$0^{\circ}C$ as a function of treatment time and oxidative gas atmosphere, and analysed by infrared spectrum and TGA. As a results of IR and TGA, it was clear that impregnated[preoxidative] PAN had 14% higher residual than untreated PAN at 100$0^{\circ}C$ and the optimal condition of stabilization was at 26$0^{\circ}C$ for 3.5 hours within $N_2$ atmosphere.
