标准摘要
[中文适用范围]： 本部分IEC 62607规定了测定垂直排列碳纳米管（VACNT）薄膜在固体基底上的关键控制特性——热扩散系数的协议。通过闪光法，从闪光灯或激光发出的光脉冲照射到固体基底上的VACNT薄膜的前表面（基底侧），然后实时监测脉冲照射后试样另一侧的温度变化。VACNT薄膜的热扩散系数可以从这种温度变化的时间变化中分析得出。该方法适用于评估可用作电子组装中热界面材料的VACNT薄膜的热传输特性。 [外文原描述]： IEC TS 62607-2-6:2024 which is a technical specification, specifies a protocol for determining the key control characteristic - thermal diffusivity for vertically-aligned carbon nanotube (VACNT) films grown on solid substrates by - flash method. A light pulse from a flash lamp or a laser is irradiated onto the front surface (substrate side) of the VACNT film on solid substrates. Then, the temperature change of the other side of the specimen is monitored in real time after the pulse irradiation. The thermal diffusivity of the VACNT film can be analysed from the time variation of this temperature change. - This method is applicable for evaluating the thermal transport properties of the VACNT films that can be used as thermal interface materials in electronics assembly.
