(What are Single-walled Carbon Nanotubes and Multi-walled Carbon Nanotubes)

What are single walled CNT and multi walled CNT?

Carbon nanotubes are another allotrope of carbon discovered after C60. Its
radial size is small, the outer diameter of the tube is generally several
nanometers to tens of nanometers, and the inner diameter of the tube is even
smaller, and some are only about 1nm; Its length is generally in the micron
level, and the length-to-diameter ratio is very large, up to 103 to 106.
Therefore, carbon nanotubes are considered as a typical one-dimensional
nanomaterial.

Carbon nanotubes can be regarded as rolled graphene sheets, so according to
the number of graphene sheets, they can be divided into: single-walled carbon
nanotubes (or single-walled carbon nanotubes, Single-walled Carbon nanotubes,
SWCNTs) and Multi-walled carbon nanotubes (or multi-walled carbon nanotubes,
MWCNTs), when multi-walled tubes begin to form, it is easy to become trap
centers between layers to capture various defects, so multi-walled carbon
nanotubes The wall of the tube is usually covered with small hole-like
defects.

Compared with multi-wall tubes, single-wall tubes have a smaller distribution
range of diameters, fewer defects, and higher uniformity. The typical diameter
of the single-walled tube is 0.6-2nm, the innermost layer of the multi-walled
tube can reach 0.4nm, and the thickest can reach hundreds of nanometers, but the
typical diameter is 2-100nm.

(2-6) The carbon nanotubes whose wall structure is composed of a single
graphite sheet closed into a tubular shape are called single-walled carbon
nanotubes (SWNT), and the carbon nanotubes whose wall structure is composed of a
plurality of graphite sheets each closed into a tubular shape and nested are
called single-walled carbon nanotubes (SWNT) Single-walled carbon nanotubes
(SWNTs). One over the other is called a multi-walled carbon nanotube (MWNT)

What is the difference between single-walled and multi-walled nanotubes?

SWNTs are made by rolling graphene sheets into seamless cylinders. MWNTs
consist of the concentration of carbon nanotubes. SWNTs require optimization of
experimental parameters for synthesis. MWNTs are easy to synthesize.

What are multi-walled carbon nanotubes used for?

Multi-walled carbon nanotubes are being considered for energy production and
storage. Graphite, carbonaceous materials, and carbon fiber electrodes have been
used for decades in fuel cells, batteries, and several other electrochemical
applications.
