Abstract: A two-step sc-SWCNT enrichment process involves a first step based on selective dispersion and extraction of semi-conducting SWCNT using conjugated polymer followed by a second step based on an adsorptive process in which the product of the first step is exposed to an inorganic absorptive medium to selectively bind predominantly metallic SWCNTs such that what remains dispersed in solution is further enriched in semiconducting SWCNTs. The process is easily scalable for large-diameter semi-conducting single-walled carbon nanotube (sc-SWCNT) enrichment with average diameters in a range, for example, of about 0.6 to 2.2 nm. The first step produces an enriched sc-SWCNT dispersion with a moderated sc-purity (98%) at a high yield, or a high purity (99% and up) at a low yield. The second step can not only enhance the purity of the polymer enriched sc-SWCNTs with a moderate purity, but also further promote the highly purified sample to an ultra-pure level.
