STUDY OF NANOCOMPOSITES OBTAINED BY CARBONIZATION OF DIFFERENT ORGANIC PRECURSORS WITHIN TAENIOLITE MATRICES

The lithium form of taeniolite served as the molecular template for ca rbon nanocomposites. It was intercalated with hydroxyaluminum and hydr oxyaluminum-zirconium cations. Aliquots of the inorganic matrices were saturated by furfuryl alcohol followed by its interlayer polymerizati on. The structures were heated at 973 K in nitrogen to carbonize the p olymeric precursor. Additional materials were mixed with polypropylene glycol which was then carbonized within the mineral layers. The surfa ce properties of the nanocomposites were studied by X-ray diffraction (XRD), DTA, SEM and sorption experiments (sorption of nitrogen). The r esults showed that structural properties of the derived materials depe nd on the inorganic matrix and organic precursor. The carbon-taeniolit e nanocomposites derived from polyfurfuryl alcohol as a precursor were characterized by high carbon content and a high percentage of its sur face area in micropores. A broad spectrum of surface characteristics o f the final products were found, depending on the history of the sampl e.
