Description
Summary:During the last decades, many researchers have tried to incorporate various kinds of metals into carbon matrices for many different purposes, such as improving the stabilization process of PAN-based carbon fibers, controlling the microtexture of carbon matrices, imparting anti-microbial properties, controlling pore structure and enhancing surface area, etc. [1,2]. For polyacrylonitrile (PAN), many earlier studies tried to make the stabilization reaction of PAN, which has been recognized as a crucial stage for the manufacture of high performance carbon fibers, much easier and/or more tractable by adding some metal particles or metal containing species in PAN precursor. However, there has been few fundamental study that systematically investigated the actual influence of metal particles on stabilization mechanism of PAN, despite that the interaction between metal species and the precursor is indicated commonly as one of the most important factors that may control the microtexture formation and the resulting performance of the product [3,4]. This study aimed therefore at deepening our understanding of the stabilization reaction of PAN precursor by elucidating the interaction behavior occurring between a metallic component and PAN precursor during heattreatment under N2 and air atmospheres, respectively, using DTA, FTIR and XPS techniques.
