研究目的
Investigating the fabrication of flexible silver nanowire transparent conductive films through an electrostatic adsorption self-assembly process.
研究成果
The electrostatic adsorption self-assembly process is a facile and effective method for fabricating flexible AgNW transparent conductive films with excellent optoelectrical properties, low surface roughness, and high reliability. The method is suitable for arbitrary shaped substrates, broadening its application in optoelectronic devices.
研究不足
The method requires precise control over the concentration of AgNW dispersion and the amount of dispersant to achieve optimal optoelectrical performance. Over-long ion bombardment time can damage the AgNW network.
1：Experimental Design and Method Selection:
The study employed an electrostatic adsorption self-assembly process to fabricate AgNW networks on flexible PET substrates.
2：Sample Selection and Data Sources:
Modified PET films with positively charged functional groups and AgNW dispersions with anionic dispersant were used.
3：List of Experimental Equipment and Materials:
Polyvinylpyrrolidone (PVP), 1,2-propylene glycol (PG), tetrabutylammonium chloride (TBAC), catechol, silver nitrate (AgNO3), Zonyl FSP, N, N0-(dimethylamino) ethyl methacrylate (DMAEMA), 1-bromododecane (R12Br), meta-sodium periodate (NaIO4), precision ion etching system (RES 101, Leica, Germany).
4：Experimental Procedures and Operational Workflow:
The process involved graft polymerization onto PET films, immersion into AgNW dispersion, and ion bombardment treatment to remove insulating dispersant.
5：Data Analysis Methods:
X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), zeta potential measurements, scanning electron microscopy (SEM), atomic force microscopy (AFM), UV-NIR spectrophotometry, and 4-point probes resistivity measurement.
