Synthesis and Characterization of MWCNT/Dolomite Hybrid Compound as Potential Composite Fillers

摘要

Multiwalled carbon nanotubes/dolomite (MWCNT/dolomite) hybrid compound was synthesized using the Chemical Vapour Deposition (CVD) technique. The catalyst was prepared via the co-precipitation method. The press involves the drying of the precipitate followed by calcination at 900°C. Upon completion of calcinations press, the reduction press was carried under H_2 at 400°C and growth in a CH_4/N_2 gas mixture at 800°C for 30 minutes The reduction press was carried out under H_2 and growth in a CH_4/N_2 gas mixture at 800°C for 30 minutes. The morphological assessment using Field Emission Scanning Electron Microscope (FESEM) showed that the CNT was successfully grown on dolomite particle. High Resolution Transmission Electron Microscope (HRTEM) micrograph further confirmed the presence of MWCNT with varied length and geometry on dolomite surfaces, supported the formation of MWCNT on the dolomite's particle.
