通过在强磁场中从悬浮液中过滤/沉积，已经制备了取向的单壁碳纳米管和纳米管绳的致密厚膜。电阻率相对于取向轴表现出适度的各向异性，而热电势在平行或垂直于该轴测量时是相同的。两个参数在两个方向上具有相同的温度依赖性。在平行方向上的热导率超过200 W/mK，在石墨的十年内。(C)2000年美国物理学会。【S0003-6951（00）05231-1】。
Dense, thick films of aligned single wall carbon nanotubes and nanotube ropes have been produced by filtration/deposition from suspension in strong magnetic fields. Electrical resistivity exhibits moderate anisotropy with respect to the alignment axis, while the thermopower is the same when measured parallel or perpendicular to this axis. Both parameters have identical temperature dependencies in the two orientations. Thermal conductivity in the parallel direction exceeds 200 W/mK, within a decade of graphite.
