Carbon Nanotubes (CNTs) and graphene exhibit extraordinary electrical
properties for organic materials, and have a huge potential in electrical and
electronic applications such as sensors, semiconductor devices, displays,
conductors and energy conversion devices (e.g., fuel cells, harvesters and
batteries). This report brings all of this together, covering the latest work
from 78 organizations around the World to details of the latest progress
applying the technologies. Challenges and opportunities with material
production and application are given.

Applications of Carbon Nanotubes and Graphene for electronics

Depending on their chemical structure, carbon nanotubes (CNTs) can be
used as an alternative to organic or inorganic semiconductors as well as
conductors, but the cost is currently the greatest restraint. However, that
has the ability to rapidly fall as new, cheaper mass production processes are
established, which we cover in this report. In electronics, other than
electromagnetic shielding, one of the first large applications for CNTs will
be conductors. In addition to their high conductance, they can be
transparent, flexible and even stretchable. Here, applications are for
displays, replacing ITO; touch screens, photovoltaics and display bus bars
and beyond.

In addition, interest is high as CNTs have demonstrated mobilities which
are magnitudes higher than silicon, meaning that fast switching transistors
can be fabricated. In addition, CNTs can be solution processed, i.e. printed.
In other words, CNTs will be able to provide high performing devices which
can ultimately be made in low cost manufacturing processes such as printing,
over large areas. They have application to supercapacitors, which bridge the
gap between batteries and capacitors, leveraging the energy density of
batteries with the power density of capacitors and transistors. Challenges
are material purity, device fabrication, and the need for other device
materials such as suitable dielectrics. However, the opportunity is large,
given the high performance, flexibility, transparency and printability.
Companies that IDTechEx surveyed report growth rates as high as 300% over the
next five years.

Graphene, a cheap organic material, is being enhanced by companies that
are increasing its conductivity, to be used in some applications as a
significantly cheaper printed conductor compared to silver ink. All this work
is covered in this new report from IDTechEx.

Activity from 78 organizations profiled

IDTechEx has researched 78 companies and academic institutions working on
carbon nanotubes and graphene, all profiled in the report. While
manufacturers in North America focus more on single wall CNTs (SWCNTs); Asia
and Europe, with Japan on top and China second, are leading the production of
multi wall CNTS (MWCNTs) with Showa Denko, Mitsui and Hodogaya Chemical being
among the largest suppliers. The split of number of organizations working on
the topic by territory is shown below.

Opportunities for Carbon Nanotube material supply

A number of companies are already selling CNTs with metallic and
semiconducting properties grown by several techniques in a commercial scale
but mostly as raw material and in limited quantities. However, the selective
and uniform production of CNTs with specific diameter, length and electrical
properties is yet to be achieved in commercial scale. A significant
limitation for the use of CNTs in electronic applications is the coexistence
of semiconducting and metallic CNTs after synthesis in the same batch.
Several separation methods have been discovered over the last few years which
are covered in the report, as is the need for purification.

Opportunities for Carbon Nanotube device manufacture

There are still some hurdles to overcome when using printing for the
fabrication of thin carbon nanotube films. There is relatively poor quality
of the nanotube starting material, which mostly shows a low crystallinity,
low purity and high bundling. Subsequently, purifying the raw material
without significantly degrading the quality is difficult. Furthermore there
is also the issue to achieve good dispersions in solution and to remove the
deployed surfactants from the deposited films. The latest work by company is
featured in the report.

Key benefits of purchasing this report

This concise and unique report from IDTechEx gives an in-depth review to
the applications, technologies, emerging solutions and players. It addresses
