摘要

我们研制了一种将碳纳米管吸附剂集成在悬浮式微量热计上的微量热计，用于痕量能物质的检测。含能物质蒸气被吸附到CNA表面上，并使用集成在微热量计上的加热器加热至微爆燃。微爆燃释放的热量提高了微热量计的温度，微热量计的温度由集成热敏电阻检测，作为高能物质的指示。CNA的巨大表面积有利于吸附含能物质，有助于实现快速吸附。微热量计能够检测2,4,6-三硝基甲苯(TNT)，检测限为2.6 pg，与不使用CNA相比，吸附时间缩短了60%。

A microcalorimeter with in-situ synthesized nanotube adsorber for trace energetic substance detection

We have developed a microcalorimeter with carbon nanotube adsorber (CNA) integrated on a suspended microcalorimeter for detection of trace energetic substance. The energetic substance vapors are adsorbed onto the CNA surfaces and are heated to micro deflagration using a heater integrated on the microcalorimeter. The released heat from micro deflagration raises the temperature of the microcalorimeter, which is detected by an integrated thermistor as an indicator of energetic substances. The huge surface areas of the CNA facilitate the adsorption to the energetic substances, and are helpful to achieving fast adsorption. The microcalorimeter is able to detect 2,4,6-trinitrotoluene (TNT) with a limit of detection of 2.6 pg and reduce the adsorption time as much as 60% compared without CNA.
