Aligned and coiled carbon nanotubes by microwave chemical vapor deposition

Abstract

Carbon nanotubes with certain shapes and 2D or 3D structures have versatile potential applications. Aligned and coiled carbon nanotubes were synthesized by microwave chemical vapor deposition. Due to its faster heating and cooling processes, microwave chemical vapor deposition can be an economic method for various carbon material fabrications. Scanning electron microscope (SEM) and transmission electron microscope (TEM) were performed to observe the micro- and nano-structure of these materials. Their properties and potential applications were also discussed.
