Now Available: Ossila's New Range of Carbon Nanotubes
Posted on Fri, Jul 07, 2017 by Jon Griffin
Ossila have released a series of carbon nanotubes, with a selection of single-walled, double-walled and multi-walled carbon nanotubes. In addition, we also offer carboxylic acid (-COOH) and hydroxyl (-OH) functionalised nanotubes.
Carbon nanotubes are the 1-dimensional form of carbon, where atoms are arranged in a hexagonal lattice (like graphene). This lattice is rolled up into elongated tubular structures (tubes) constraining the lattice to extend effectively in one direction. These tubes can either be single-walled or have several tubes nested within each other. The properties of these nanotubes depend on the orientation of the hexagonal lattice. Depending upon this lattice orientation, single-walled carbon nanotubes can be either semiconducting or metallic.
See our range of single-walled carbon nanotube powders.
Carbon nanotubes have excellent mechanical, electrical, thermal, and optical properties. When added to form composite materials, their properties can be used to modify those materials. For more information about these properties, please see the 'What are single-walled carbon nanotubes?' section on our product page.
Functionalisation of the carbon nanotubes can improve its properties such as its dispersability in solvents, or to provide potential biochemical functionality to the surface of the nanotubes. Functionalisation of the outer wall of double- or multi-walled carbon nanotubes does not alter the properties of the inner tubes, allowing them to retain their unique properties after being functionalised.
Ossila offer carboxylic acid (-COOH) and hydroxyl (-OH) functionalisation for our range of nanotubes. Visit our range of double-walled and multi-walled nanotube powders, with -COOH and -OH functionalisation options.

Jonathan joined Ossila in July 2016 after working as a post-doctoral research associate at the University of Sheffield. During his career as a research scientist, he has worked in a wide range of areas including organic light-emitting diodes, organic photovoltaics, transparent conductors, organic lead-halide perovskites, and scale-up processes in thin-film fabrication. As part of his role at Ossila, Jonathan is responsible for the technical support for several material ranges, including perovskites, organic photovoltaics, graphene and other 2-D materials. In addition, he is also involved in the development of new equipment and product ranges.
