摘要：

We demonstrate the separation of high-purity, long semiconducting single-wall carbon nanotubes (s-SWCNTs) by single-stage gel filtration. Semiconducting SWCNTs are preferentially adsorbed on an allyl dextran-based gel column and then eluted with surfactant solution at a rate that depends on nanotube length as well as electronic type of nanotubes. These differences allow the separation of length-sorted and purity-enhanced s-SWCNTs by fractionated collection of the eluate, which provides the desired nanotubes for electronic device applications.
