A high-performance hydrogen gas sensor using Pd-decorated and porous conducting polymer |
| 초록 |
A novel method for fabricating Pd-decorated nanoporous poly(aniline-co-aniline-2-sulfonic acid):poly(4-styrenesulfonic acid) (P(ANI-co-ASA):PSS) nanostructures and their use as sensing elements for hydrogen (H2) gas sensors are demonstrated in this presentation. Both co-monomers and PSS provide sufficient –SO3H groups to effectively anchor palladium nanoparticles and lead to enhanced interactions with H2 gas, while retaining the charge transport properties of the P(ANI-co-ASA):PSS. The pores enlarged the surface area available for interaction with the H2 gas molecules, resulting in much higher sensitivity compared with both the non-porous Pd-decorated P(ANI-co-ASA):PSS and the pristine P(ANI-co-ASA):PSS. |
