Multiwalled carbon nanotube (MWCNT) felts are prepared by catalytic decomposition of methane over an aerogel catalyst. The graphitized MWCNT felts are then densified in a CVD furnace. The morphology and the structure of the MWCNT felt and its CVD-densified product were investigated by SEM, TEM, XRD and Raman spectroscopy. The CVD-densified MWCNT felt has a higher bulk density and thermal conductivity than that of the corresponding high temperature treated MWCNT felt.
