Description générale

Produced using CHASM′s patented CoMoCAT™ synthesis technology, Signis® SG65 is a single-wall carbon nanotube (CNT) product uniquely enriched in semiconducting tubes, with (6,5) chirality being most abundant. Approximately 95% of the CNTs in SG65 are semiconducting with approximately 41% of those tubes being (6,5) chirality.
