Abstract
Herein, we synthesized four sensing materials namely N-MWCNT, N-MWCNT/CMC, N-MWCNT/PANI, and N-MWCNT/PPy, and characterized them using FTIR, XRD, XPS, SEM, and TEM. Then, we studied the effect of polymers such as CMC, PANI, and PPy on the N-MWCNT for the detection of DMMP with a concentration ranging from 2–10 ppm. The results showed that N-MWCNT alone possesses the lowest sensitivity towards 10 ppm DMMP molecules. When the polymers were added to the N-MWCNT, the results showed enhancement in the sensitivity towards the DMMP molecules. The order of highest sensitivity is N-MWCNT/CMC > N-MWCNT/PANI > N-MWCNT/PPy > N-MWCNT.
