Abstract

We demonstrate a new method that makes use of colloidal silica templates to fabricate porous three-dimensional architectures of carbon nanotubes (CNTs). CNTs were grown on monolayered and multilayered structures of colloidal silica using chemical vapor deposition. Porous CNT membranes and three-dimensional carbon nanotube foams were obtained by treating these silica-CNTs structures with HF. The membranes and foams of CNT so obtained were chemically and mechanically stable and were characterized by using scanning electron microscopy and energy dispersive spectroscopy.

摘要

我们展示了一种利用胶体二氧化硅模板制造碳纳米管（CNT）多孔三维结构的新方法。通过化学气相沉积法在单层和多层胶体二氧化硅结构上生长碳纳米管。用氢氟酸处理这些二氧化硅-碳纳米管结构，得到了多孔碳纳米管膜和三维碳纳米管泡沫。如此获得的碳纳米管膜和泡沫在化学和机械性能上是稳定的，并通过扫描电子显微镜和能量色散光谱进行了表征。
