The results show that the sensing of volatile organic compounds by functionalized nanotubes considerably increases with respect to pristine nanotubes. The increase is highly dependent on used vapor polarity. For the case of highly polar methanol, the functionalizedMWCNT network exhibits even more than eightfold higher sensitivity in comparison to the network prepared from pristine nanotubes.
