研究目的
To synthesize and characterize PANI composites with calcium carbonate and Au/Ag NPs for enhanced electrochemical and antibacterial properties.
研究成果
PANI composites with CaCO3 and Au/Ag NPs were successfully synthesized and characterized. The composites showed enhanced conductivity and good antibacterial activity against E. coli and S. aureus. The method is simple and cost-effective, suitable for nanoparticle coating applications.
研究不足
The study focuses on the synthesis and characterization of PANI composites with limited exploration of their application in real-world scenarios. The antibacterial activity was tested against only two types of bacteria.
1：Experimental Design and Method Selection:
PANI was synthesized by solution mixing technique using aniline polymerization in conc. HCl with ammonium persulfate as oxidant/initiator. Composites of PANI with CaCO3 and Au/Ag NPs were prepared by mixing components under appropriate conditions.
2：Sample Selection and Data Sources:
Samples were prepared with varying amounts of PANI, CaCO3, and Au/Ag NPs as detailed in Table
3：List of Experimental Equipment and Materials:
FTIR spectrophotometer, SEM model JSM 6490 LV, EDX 133 EV Dry Detector, CH instrument 604E USA for cyclic voltammetry, Kiethley 236 Current Source-meter for DC conductivity measurements.
4：Experimental Procedures and Operational Workflow:
Synthesis involved polymerization of aniline, preparation of CaCO3 microparticles, synthesis of Au/Ag NPs in ionic liquid, and preparation of PANI-CaCO3-Au/Ag nanocomposites. Characterization was done using FTIR, SEM, EDX, and electrical conductivity measurements.
5：Data Analysis Methods:
FTIR spectra analysis, SEM and EDX micrograph analysis, cyclic voltammetry for electrochemical activity, impedance spectroscopy for AC conductivity, and DC conductivity measurements.
