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.[1][2][3][4][5][6][7]
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.[8]SWNTs on poly methyl methacrylate (PMMA) substrates may be used as transducers for electrochemical microfluidic sensing.[9]
