作为技术规范的IEC TS 62607-2-6:20 24规定了用于确定关键控制特性的协议 -热扩散率 对于在固体衬底上生长的垂直取向碳纳米管(VACNT)薄膜 -闪光法。 将来自闪光灯或激光的光脉冲照射到固体基板上的VACNT膜的前表面(基板侧)上。然后，在脉冲照射后实时监测试样的另一侧的温度变化。可以根据该温度变化的时间变化来分析VACNT膜的热扩散率。 -该方法适用于评估可用作电子组件中的热界面材料的VACNT膜的热传输性质。

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.
