研究目的
Investigating the effect of surface amphiphilic property of azobenzene self-assembled electrode materials on the properties of supercapacitors.
研究成果
The surface hydrophilic properties and the specific capacitances of azo-Cn increased with the tail chain length n decreasing, indicating that azo-C8 with good supercapacitive characteristics could be the potential ideal electrode materials for low-cost and high-efficiency electrochemical supercapacitors.
研究不足
The study focuses on the effect of surface amphiphilic property on supercapacitor properties, but other factors such as electrode material composition and electrolyte properties may also influence the results.
1：Experimental Design and Method Selection:
Novel azobenzene self-assembled complexes (azo-Cn, n = 8, 12, 16) were used as an electrode material for pseudo-capacitors. Nickel foam was used as substrates and current collectors.
2：Sample Selection and Data Sources:
Methyl orange (Azo) and N-alkyl trimethyl ammonium bromide (Cn, n = 8, 12, 16) were used as received.
3：List of Experimental Equipment and Materials:
X-ray diffraction (XRD) diffractometer, differential scanning calorimetry (DSC), thermogravimetry (TG), polarized optical microscope (POM), Gamry Reference 3000 electrochemical work station.
4：Experimental Procedures and Operational Workflow:
The working electrode was prepared by mixing azo-Cn in chloroform with acetylene black and PTFE glue, then coated onto nickel foam, compacted, and dried.
5：Data Analysis Methods:
Cyclic voltammetry (CV), galvanostatic charge-discharge, and electrochemical impedance spectroscopy (EIS) measurements were performed.
