中文摘要：

实验研究了不同温度（258．15K～270．15K）、不同纳米碳管含量（0．1wt％～10wt％）以及有无分散剂十二烷基硫酸钠（Sodium Dodecyl Sulfate，SDS）情况下四氢呋喃（Tetrahydrafuran，THF）水合物的导热系数。结果表明：THF水合物的导热系数随纳米碳管含量的增加而显著增加，纳米碳管的加入并没有改变THF水合物导热系数随温度的玻璃体变化特性。在纳米碳管质量分数一定时，随着温度的升高，THF水合物导热系数增大的速率越来越快。对于含纳米碳管的THF水合物，不加分散剂时的导热系数比加分散剂的导热系数低，但高于纯THF水合物的导热系数。

英文摘要：

Thermal conductivity of Tetrahydrofuran hydrate was measured at different ternperature（258. 15K- 270. 15K）, at different carbon nanotupes mass fraction（0. 1wt% - 10wt%）, with and without dispersant （Sodium Dodecyl Sulfate, SDS） .The results indicate that thermal conductivity of THF hydrate increases with increasing carbon nanotubes mass fraction, THF hydrate containing carbon nanotubes is also glass - like material. At a certain carbon nanotupes mass fraction, the velocity of enhancement of thermal conductivity of THF hydrate increases with increasing temperature. Thermal conductivity of THF hydrate containing carbon nanotupes without dispersant is lower than that with dispersant, but it is higher than THF hydrate not containing carbon nanotupes.
