A large contrast in the electrical and thermal conductivities via a first order phase transition in surface-functionalized carbon nanotube(CNT)/hexadecane composites is reported. Surface modification of the CNTs improves the electrical conductivity contrast and the stability of the composites. We demonstrate that, with these composites, the electrical conductivity changes above 10(5) times and the thermal conductivity varies up to 3 times at 18 °C.
据报道，通过表面功能化的碳纳米管（CNT）/十六烷复合材料中的一级相变，实现了电导率和热导率的大幅对比变化。CNT 的表面改性提高了复合材料的电导率对比和稳定性。我们证明，在这些复合材料中，电导率变化超过 10(5)倍，在 18°C 时热导率变化高达 3 倍。
