Electrical properties and glass transition temperature of multiwalled carbon nanotube/polyaniline composites

► MWCNT/PANI composite was synthesized and doped with 0, 2, 4 and 16 wt.% of pure and functionalized MWCNTs. ► The resistivity of the composites was lower than that of the pure PANI at all temperatures. ► By increasing the amount of functionalized MWCNTs in PANI, its Tg was increased. ► By increasing the pelletization pressure, the bulk resistivity decreased but the Tg increased.
