General description

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

  • Electronics
  • Sensors
  • Composites
  • Energy Storage
  • Study of Life Science systems

氮化硼纳米管(BNNT)是碳纳米管(CNT)的结构类似物,而碳纳米管是高纵横比纳米管材料,其中碳原子被氮原子和硼原子交替取代。

A nanocomposite is typically defined as a mixture between a host material (e.g., polymer matrix) and nanofillers with at least one dimension of less than 100 nm.

Boron nitride nanotubes (BNNTs) are structural analogs of carbon nanotubes, with alternating boron and nitrogen atoms replacing carbon.
