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
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.
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.
