研究目的
Investigating the production and characterization of self-assembled films based on polyaniline grafted with reduced graphene oxide and polystyrene sulfonate for potential electrochemical applications.
研究成果
The SA films fabricated using PAni-rGO composites showed significant improvement in electrochemical properties, with the PAni-1%rGO/PSS film exhibiting the best performance. This indicates the potential of these films for applications in sensors and charge storage devices.
研究不足
The study focused on the electrochemical properties of the films but did not explore their long-term stability or performance under varying environmental conditions.
