Carbon nanotube (CNT) was found in 1991 by Dr. Iijima, and it have attracted wide attention because of its high mechanical properties along with high electrical and thermal conductivities. However, practical application of carbon nanotube has not been achieved yet. In this article, I repot promising applications of CNT and rubber composite such as high thermal conductive flexible sheet (TIM), stretchable electric wire for devices, high wear resistant material and high thermal durable materials for shielding field. Furthermore, I also report the importance of CNT dispersion for getting high performance the CNT and rubber composite. Just after the synthesis, CNTs form bundled structure. To derive the structural advantage of CNT for filler, de-bundling is important.
