Abstract
Herein, we prepared a multi-walled carbon nanotube (MWCNT) paper by filtration, and tested its gas-sensing ability toward polar and non-polar organic solvents by comparing the magnitude of the adsorption sensitivity, response time, and reproducibility. The adsorption of non-polar organic solvents showed multilayered behavior; we presume that a stable adsorption layer is prevented from being formed owing to the measurement temperature used being higher than the critical gas temperature.
