請你搜索這個文獻(xiàn)。目前國內(nèi)是沒有辦法測量的,碳管需要需要微機(jī)械臂搭在兩個熱源之間,由于靜電的作用,極其容易斷裂。其中的第一作者是九州大學(xué)的 Fujii Motoo,第二作者是清華的張興教授,第三作者是上海第二工業(yè)大學(xué)的謝華清教授。 Phys Rev Lett. 2005 Aug 5;95(6):065502. Epub 2005 Aug 2. Measuring the thermal conductivity of a single carbon nanotube. Fujii M1, Zhang X, Xie H, Ago H, Takahashi K, Ikuta T, Abe H, Shimizu T. Abstract Although the thermal properties of millimeter-sized carbon nanotube mats and packed carbon nanofibers have been readily measured, measurements for a single nanotube are extremely difficult. Here, we report a novel method that can reliably measure the thermal conductivity of a single carbon nanotube using a suspended sample-attached T-type nanosensor. Our experimental results show that the thermal conductivity of a carbon nanotube at room temperature increases as its diameter decreases, and exceeds 2000 W/mK for a diameter of 9.8 nm. The temperature dependence of the thermal conductivity for a carbon nanotube with a diameter of 16.1 nm appears to have an asymptote near 320 K. The present method is, in principle, applicable to any kind of a single nanofiber, nanowire, and even single-walled carbon nanotube. |
