Examination of the chemical mechanism during thermal treatment of carbon fiber PAN precursors

By synthesis of isotopically labelled PAN precursors (2H, 15N, 13C) including their copolymers (with methylacrylate, itaconic acid?) and examination of the structural changes of them during thermal treatment by means of IR and NMR spectroscopy, DSC measurement and TG/GC/MS analysis the mechanism and elemental chemical reactions for the formation of efficient carbon fibers is worked out.
The knowledge about the detailed reaction pathways leading to most-efficient final carbon fiber material is still very limited. Thus, it is extremely difficult for carbon fiber producers (e. g. SGL Carbon) to systematically improve their products.
The chemically oriented work will include the synthesis and characterization of precursor polymers and copolymers and their thermal treatment as well as the synthesis and analysis of small model compounds.
