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
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.SWNTs on poly methyl methacrylate (PMMA) substrates may be used as transducers for electrochemical microfluidic sensing.
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.
