The bundling state of several dry single-walled carbon nanotube (SWNT) samples is compared using isothermal microcalorimetry (IMC). So as to get different dry samples with various bundling states, the pristine SWNTs were pretreated with a solution of an aromatic amphiphile with or without sonication, washed and dried before being studied by IMC. The bundling state of the different SWNT samples, which was first analyzed by TEM, was then correlated to the obtained IMC data thanks to the interpretation of the observed energy transfer phenomena. From our results, IMC appears to be an interesting technique for the surface probing of dry SWNT samples, and herein for the evaluation of the bundling state.
使用等温微量热法（IMC）比较了几个干燥的单壁碳纳米管（SWNT）样品的聚集状态。为了获得具有不同聚集状态的不同干燥样品，将原始单壁碳纳米管先用含有或不含超声处理的芳香族两亲物溶液进行预处理，洗涤并干燥后再通过等温微量热法进行研究。不同单壁碳纳米管样品的聚集状态首先通过透射电子显微镜（TEM）进行分析，然后通过对观察到的能量转移现象的解释，将其与获得的等温微量热法数据相关联。从我们的结果来看，等温微量热法似乎是一种用于干燥单壁碳纳米管样品表面探测的有趣技术，在此用于评估聚集状态。
