Abstract

A method for the non-destructive purification of single-walled carbon nanotubes (SWNTs) using classical coordination chemistry to remove the metal catalyst has been developed. In preliminary tests, the conductivity of fi lms based on the resulting SWNTs was markedly better than that of fi lms prepared from SWNTs purifi ed by treatment with oxidizing acid solutions. The transparent and conducting SWNT fi lms have potential applications in optoelectronic devices.
