일반 설명

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).

애플리케이션

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.

Manufacturing, Characterization and Use of Single Walled Carbon Nanotubes

Carbon nanotubes are materials that possess remarkable properties and offer extraordinary possibilities.

Sorting Carbon Nanotubes and Their Biological Applications

Carbon nanotubes (CNTs) have received much attention since their discovery in 1991 by Sumio lijima1 due to their excellent mechanical, electrical, and optical properties.

3D Printable Conductive Nanocomposites of PLA and Multi-walled Carbon Nanotubes

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.

Polymer-Sorted Semiconducting Carbon Nanotubes for Transistors and Solar Cells

Single-walled carbon nanotubes (SWCNTs) are promising materials for use in the active channel of field-effect transistors (FETs), photoabsorbing layers of solar cells and photodetectors because of their ultrafast charge transport mobility.
