研究目的
To address the thermal instability, rough surface topography, and poor interfacial adhesion of silver nanowire-based flexible transparent electrodes by developing a robust and washable FTE based on AgNW@TiO2 core-shell network embedded in polyimide substrate.
研究成果
The AgNW@TiO2 core-shell network significantly enhances thermal stability, electrical and optical properties, and when embedded in PI, provides a robust, washable FTE with high mechanical flexibility, low surface roughness, and excellent stability under various stresses, making it suitable for next-generation wearable electronics.
研究不足
The TiO2 shell is amorphous and may have limited crystallinity at lower temperatures; the solution-based method may not achieve the same uniformity as vacuum-based methods like ALD; the study focuses on specific AgNW dimensions and may not generalize to all nanowire sizes.
1:Experimental Design and Method Selection:
The study employs a solution-based process to fabricate AgNW@TiO2 core-shell networks and embed them in polyimide substrates. The design rationale includes using TiO2 sol to coat AgNWs for thermal stability and embedding in PI for mechanical robustness and smooth surface.
2:Sample Selection and Data Sources:
AgNWs with diameter 25-35 nm and length 15-20 μm from Zhejiang Kechuang Advanced Materials Co., Ltd. are used. Other materials include isopropyl alcohol, titanium isopropoxide, hydrogen peroxide, deionized water, and PI precursors.
3:List of Experimental Equipment and Materials:
Equipment includes Mayer rod for coating, spin coater, annealing oven, doctor blade, Loresta AX MCP-T370 4-probe tester, Jinhua UV1800PC spectrophotometer, Shimadzu UV-3101 spectrophotometer, LICHEN NDJ-8S viscosity tester, METTLER TOLEDO TGA/SDTA851e, FEI HELIOS Nanolab 600i SEM, FEI Tecnai G2 F30 TEM, Bruker Dimension FastScan AFM, Bruker D8 Advance XRD, and Keysight B2902A precision source.
4:Experimental Procedures and Operational Workflow:
AgNWs are coated on glass using Mayer rod, annealed, treated with TiO2 sol via spin coating, annealed again, PI precursor is flowed using doctor blade, and cured through sequential annealing. The FTE is lifted off to form a free-standing film.
5:Data Analysis Methods:
Sheet resistance is measured with 4-probe tester, transmittance with UV-Vis spectrophotometer, haze with integrating sphere, viscosity with rotational viscometer, TGA for thermal analysis, microstructures with SEM/TEM/AFM, XRD for crystal structure, and resistance variation during bending with homemade system.
