2019年6月11日 · Polypyrrole (PPy) nanorods (NRs) and nanoparticles (NPs) are synthesized via electrochemical and chemical methods, respectively, and tested upon ammonia exposure using Raman and X-ray ...

2015年10月1日 · Five different polypyrroles (PPys) with four different oxidants, namely, FeCl3, FeCl 3 ·6H 2 O, Fe 2 (SO 4) 3, and (NH 4) 2 S 2 O 8, were prepared by chemical oxidative polymerization and studied during aging. In the case of FeCl 3, the anionic surfactant dodecylbenzenesulfonic acid (DBSA) was used as a co-dopant to improve the stability.

Characterization of both nanomaterials via Raman spectroscopy demonstrates the formation of PPy, displaying vibration bands consistent with the literature. Additionally, XPS reveals the presence of neutral PPy species as major components in PPy NRs and PPy NPs, and other species including polarons and bipolarons.
