The single-walled carbon nanotubes (SWNTs) have been attention as promising materials for many potential applications due to their excellent mechanical and electrical properties. The raw SWNTs have a mixture of semiconducting and metallic nanotubes, which hinders their electronic devices application in semiconductor-based electronics. Sorting by conjugated polymers is a simple, selective, and scalable process. Various alternative solvents are studied, namely, decalin, mesitylene, tetralin, and cumene for the dispersion of large diameter SWNTs (diameter > 1.1nm) by full name (PFDD). The possibility to perform selective sorting of semiconducting SWNTs using various solvents provides a greater diversity of semiconducting SWNT ink properties, such as boiling point, viscosity, and surface tension as well as toxicity. The yield and purity of semiconducting SWNTs are analyzed by optical absorption. Our study may also enable more environmentally friendly processing of sorted SWCNTs for printed electronics applications.
