Case Study

Enabling Precision Electronics with Inkjet-Printed Silver Nanowire Circuits

Finn, David J., et al. ACS applied materials & interfaces 7.17 (2015): 9254-9261.

Challenge: Printed electronics demand high-conductivity, patterned transparent electrodes compatible with flexible substrates. Existing solution-processing techniques struggle to achieve precise patterning while maintaining optimal conductivity and low-temperature processing requirements.
Solution: Development of an advanced inkjet printing platform using optimized silver nanowire (Ag NW) dispersions in isopropyl alcohol-diethylene glycol solvent. This enables direct deposition of high-performance conductive patterns without high-temperature sintering.
Key Results:
· Precision Ink Formulation: Engineered solvent ratio ensures stable jetting and controlled evaporation; Enables 10-20 printing passes for controlled thickness (0.5-2 μm); Maintains nanowire integrity during deposition.
· Patterned Electrode Performance: Achieves 8 Ω/□ sheet resistance at 1-10 mm line widths; Delivers 105 S/m conductivity - competitive with reported standards; Maintains processing temperatures ≤110°C. Provides semitransparency with DC/optical conductivity ratio ~40.

Ultra-Light Silver Nanowire Aerogels for Next-Generation Functional Materials

Qian, Fang, et al. Nano letters 17.12 (2017): 7171-7176.

Challenge: Ultra-lightweight materials with metal-like conductivity and structural integrity are needed for advanced aerospace, biomedicine, and energy storage applications. However, conventional metal foams suffer from either limited conductivity or reduced mechanical stability at ultra-low densities and have little architecturally tunability.
Solution: Development of precision-engineered silver nanowire (Ag NW) aerogels through freeze-casting and thermal sintering technology, delivering excellent performance with tunable anisotropic structures.
Key Results:
· Directed Assembly Technology & Junction Optimization: Vertical freeze-casting creates anisotropic microchannels using liquid nitrogen temperature gradients; Ice-templating aligns NWs into mechanically reinforced lamellar structures; Lyophilization preserves 3D porous architecture without collapse. 250°C hydrogen sintering welds nanowire junctions; Removes polymer surfactants while enhancing conductivity.
· Breakthrough Performance: Density is precisely controlled by nanowire concentration, as low as 4.8 mg/cm3, and conductivity is as high as 51 000 S/m. Silver nanowire aerogels exhibit "elastic hardening" behavior with a Young's modulus of up to 16 800 Pa.
