| dc.description.abstract | Polyaniline (PANI) and a polyaniline derivative (poly (2,5-dimethyl aniline)) were evaluated for their sensitivity towards formaldehyde. Among the two polymer backbones evaluated, polyaniline seemed more sensitive towards formaldehyde. Therefore, to further enhance sensitivity towards formaldehyde, polyaniline was doped with different weight percentages of indium oxide and further evaluated for its sensing capabilities such as sensitivity, selectivity, and stability. It was found that PANI with 1.25 wt.% of In2O3 was most sensitive towards formaldehyde, while PANI with 5 wt.% of In2O3 was most selective towards formaldehyde over benzene interferent. It was observed that sensitivity and selectivity trends for PANI doped with different wt.% of In2O3 were reverse of each other. All sensing materials were found stable. | en |
