In carbon nanotube (CNT) polymer composites, the small thermal capacitance of the polymer and high thermal conductivity of the CNTs enable rapid heating, Highly conducting polydimethylsiloxane (PDMS) nanotube composites with different aspect ratios of CNT were investigated to observe their electrical heating behavior. The electrical conductivity of the CNT/PDMS composite with higher ratio CNTs showed the conductivity up to two orders of magnitudes larger than the composites with lower aspect ratio CNTs. Moreover, the degree of negative temperature coefficient of resistance originating from the interconnection resistance between the CNTs could be dramatically increased by using higher aspect ratio CNTs.
