General description

Produced using CHASM′s patented CoMoCAT synthesis technology, Signis® CG100 is an economical single-wall carbon nanotube product, offering good electrical conductivity and high carbon purity.

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 conductive coatings where tight control of chirality is not critically important.
