“…It is quite clear that the Pd(II) is the main state of the palladium deposited on the polyaniline surface. This result is rather different from what we reported earlier where Pd(II) can be reduced to Pd(0) by chemically synthesized polyaniline in the fully reduced state in the form of powder or free-standing film after 180 min (38). The plasma-polymerized polyaniline comprises chains shorter than those of the chemically synthesized polyaniline, and the ability of the former to reduce the metal salt is decreased.…”

“…9a, the component peak of Au 4f at 84 eV confirms the presence of Au(0) (37). Thus, the plasmapolymerized polyaniline has a similar ability as the chemically synthesized polyaniline to reduce Au(III) to Au(0) (38). The sheet resistance of this metallized polyaniline on AAc-g-LDPE goes down to about 10 8 /sq.…”

“…1 shows a schematic illustration of the fabrication process of the Pd/PPy/PAN composite nanobers. As the standard reduction potential of PdCl 4 2À /Pd is 0.591 V, 35 while the oxidation potential of pyrrole monomer is 0.2 V, 36 2, it can be seen that the pure PAN nanobers show a peak at about 16.9 , which corresponds to the orthorhombic PAN (110) Bragg reection. 38 However, this peak disappears aer the formation of Pd NPs and PPy.…”

“…At first, AuCl 4 – is reduced to from gold nuclei, which further grow to be gold nanoparticles and microclusters, while the conductive polypyrrole is oxidized to a higher oxidation state by deprotonation. The overall reaction can be represented as Eqn according to some related researches:

{([], ((), C_{4} H_{2}) NH)}_{X} + {AuC1}_{4}^{-} \to {([], ((), C_{4} H_{2}) normalN)}_{X} + AU + {4C1}^{-} + {XH}^{+}

Without any other additives or additional energy, Au nanoplates have been successfully prepared and integrated simultaneously with the dedoped polypyrrole nanofiber film via the in situ reduction of AuCl4– on the film surface. The morphology and structure of the as‐prepared composite film are characterized, and its application for surface‐enhanced Raman scattering is also investigated. It has been found that the morphology of as‐prepared Au nanoplates is dependent on the reaction duration, while the density is dependent on the concentration of AuCl4– ions in the reaction process. It is suggested that polypyrrole plays dual reducing and structure‐directing roles during the formation of Au nanoplates. Surface‐enhanced Raman scattering study shows that the Au nanoplates give an intensive and enhanced Raman scattering when 4‐aminothiophenol is used as a probing molecule. The employed approach may shed some light on simultaneously fabricating and immobilizing other noble metal micro/nanostructures with unique morphology. Copyright © 2011 John Wiley & Sons, Ltd.
