ORGANOTITANIUIM PRECURSORS, METHOD FOR THEIR PREPARATION AND METHOD OF PRODUCING MATERIAL AND/OR COMPOSITE MATERIAL USING THE SAME

摘要

The invention concerns organotitanium precursors comprising polymer and titanium chlorides, both dissolved in organic solvent. The titanium chlorides are preferably TiC12 and/or TiC13 and/or (C2H5)2TiCl2. The polymer is prefcrably polyimide PI and/or polyamide PA and/or polybenzimidazole PBI and/or polyacrylonitrile PAN and/or polyethylene terephthalate PET and/or polyvinyl chloride PVC. The solvent is preferably CCI4 and/or acetonitrile CH3CN and/or chlorobenzene C6H5C1 and/or N,N-dimethylformamide (DMF) and/or dimethyl sulphoxide (DMSO) and/or tetrahydrofuran (THF-) and/or dimethylacetamide (DMAA) and/or N,N-diethylformamide (DEF). A second aspect concerns a method of producing, the organotitanium precursor, whereby the polymer is dissolved in the organic solvent, the obtained solution is mixed and the titanium chlorides are added, the mixture is kept under an inert gas atmosphere at constant temperature until it homogenises, after which the solution is cooled to ambient temperature the thus-obtained dense liquid is maintained in a dry inert gas atmosphere. The final aspect of the invention concerns a method of producing titanium carbides and/or titanium nitrides and/or titanium carbonitrides and/or carbon and/or nitrides and/or carbonitrides and/or semi-metals from the organotitanium precursors by heat treating the precursors at 300-2000°C in an inert- gas or reactive gas atomosphere.
