One-step synthesis of polypyrrole-Ag nanofiber composites in dilute mixed CTAB/SDS aqueous solution

摘要

Polypyrrole (PPy)—Ag nanofiber composites were synthesized with one step by the redox reaction between silver nitrate and pyrrole monomer in dilute mixed cetyltrimethyammonium bromide (CTAB)/sodium dodecyl sulfate (SDS) aqueous solution. The morphology and structure of the resulting composites were investigated by SEM and TEM images, FT-IR, Raman and XRD spectra, respectively. The results showed a strong compound interaction existing between PPy nanofibers and Ag nanoparticles.
