摘要

报道了用脉冲微等离子体在装有特殊放电电池的扫描电子显微镜腔内合成碳纳米材料的方法。甲烷微等离子体的峰值电流密度大于5 kA cm−2，脉冲宽度接近10 ns。5 s后，在铂膜的正极上除了熔斑外，还可以观察到一些碳纳米材料的沉积。

Fabrication of carbon nanomaterials using pulse microplasma in SEM

Synthesis of carbon nanomaterials by pulse microplasma in the chamber of a scanning electron microscope equipped with a special discharge cell is reported. The peak current density of the methane microplasma was higher than 5 kA cm−2, and the pulse width was almost 10 ns. After 5 s operation, there could be observed some carbon nanomaterials deposited on the cathode of the platinum film besides melted spots.
