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.[1][2][3][4][5][6][7]
Suitable for use in conductive coatings where tight control of chirality is not critically important.

Preparation Note

CoMoCAT™ Catalytic Chemical Vapor Deposition (CVD) Method
