General description

Produced using CHASM′s patented CoMoCAT™ synthesis technology, Signis® CG200 is the company′s largest-diameter single-wall carbon nanotube product.
Tube diameter determined by fluorescence spectroscopy.

Application

Manufacturing, Characterization and Use of SWCNTs
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 conductive composites and coatings.Functionalized single-walled carbon nanotubes (SWNTs) embedded in an insulating polymer matrix may be used as stable hole collection layer in perovskite solar cells.
