| General description【一般描述】 | We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here. Structure of double walled carbon nanotubes (DWNTs) can be imagined as a two coaxial concentric single walled carbon nanotubes (SWNTs). It has been prepared by catalytic chemical vapor deposition. DWNTs exhibit excellent field emission properties and may be potentially useful as field emission displays (FEDs) and field emission transistors (FETs). |
| Application【应用】 | Carbon nanotube, double walled can be used for a variety of applications such as solar cells, nanomechanical resonators, film heaters, biosensors, and field emission displays. |
| Preparation Note【制备说明】 | Chemical Vapor Deposition (CVD) Method |
| Analysis Note【分析说明】 | DWNT 占 50-80%，其他 CNT 占 10-40%，其余的为为无定形碳和残留的金属催化剂。 |
