제목 Fabrication of Pd-decorated and Highly Porous Conducting Polymer Nanostructures as Effective Transducer to Hydrogen Gas
초록 High-performance hydrogen (H2) gas sensors was produced by incorporating nanoporous structures with the Pd-decorated poly(aniline-co-aniline-2-sulfonic acid):poly(4-styrenesulfonic acid) (P(ANI-co-ASA):PSS) nanostructures. Sufficient –SO3H groups, which were provided by both co-monomers and PSS, consequently led to enhanced interactions with H2 gases. The pores of 10–30 nm in diameter were readily formed on the Pd-decorated P(ANI-co-ASA):PSS surfaces by introducing water-soluble porogen agents and consequently enlarged the surface area available for interaction with the H2 gas molecules. The nanoporous Pd-decorated P(ANI-co-ASA):PSS exhibited much higher sensitivity (5 ppm) compared with both the non-porous Pd-decorated P(ANI-co-ASA):PSS (50 ppm) and the pristine P(ANI-co-ASA):PSS (50 ppm).
