Abstract

A low temperature route (200-600°C) to the preparation of glassy carbon containing high levels of heteroatoms has been developed. The synthesis involves the preparation of diacetylenic oligomeric precursors, molding of these materials, and thermal treatment under controlled conditions to form glassy carbon. Materials have been prepared which contain high levels (10-15%) of nitrogen, fluorine, and silicon by covalent attachment of these heteroatoms to the diacetylene oligomers. A Raman study confirmed the presence of diagnostic peaks for glassy carbon, including the E1g fundamental at 1582 cm-1 and the A1g at 1360 cm-1. The physical properties of these materials, including thermal stability, microscopic structure, density, and elastic modulus are reported.
