General description

Produced using CHASM′s patented CoMoCAT technology, Signis® SG76 is selectively enriched in (7,6) chirality.
Tube diameter determined from an optical absorbance spectrum and AFM.

Application

Carbon nanotube, single-walled (SWNT) belongs to the class of carbonaceous materials with excellent physiochemical, thermo-mechanical and electrochemical properties. This material can be used in a variety of sustainable energy applications such as solar cells, photocatalysis, thin film conductors, field effect transistors (FETs), biosensor, gas sensor, supercapacitor and nanomechanical resonators.
Suitable for use in coatings for printed electronics, photovoltaics, medical applications.SWNTs (7,6 chirality) was used to prepare SWNT buckypapers, which were used as electrocatalyst supports for the electro-oxidation of methanol.SWNTs on poly methyl methacrylate (PMMA) substrates may be used as transducers for electrochemical microfluidic sensing.

Articles

This article gives a brief overview of the physico-chemical nature and characterization of single-walled nanotubes (SWNTs).

The CoMoCAT® method of single-walled carbon nanotube (SWNT) synthesis yields high purity SWNTs with specific chiralities and narrow distributions of tube diameters.

Single-Walled Carbon Nanotubes synthesized by the Super-Growth Method & their properties & applications, including dispersing SGCNTs, SGCNT-polymer composites & SGCNT-metal composites are discussed.

Protocols

The dispersibility and bundle defoliation of single-walled carbon nanotubes (SWCNTs), which can be applied to materials produced by the CoMoCAT® process, have been extensively investigated by SouthWest NanoTechnologies (SWeNT ®) and at the University of Oklahoma.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
