High-yield photolytic generation of brominated single-walled carbon nanotubes and their application for gas sensing

Abstract

We present a facile and efficient photobromination technique for the covalent sidewall functionalization of SWNT using N-bromosuccinamide as the bromine source. The modified bromine functionalized SWNTs are used as active agents in a resistance measuring electrode system for sensing and discrimination of analyte vapors.
