Product Detail

ACS Material silver nanowires (AgNWs) are high-aspect-ratio metal nanowires that combine high optical transmittance with low sheet resistance, making them a flexible, solution-processable alternative to brittle ITO for transparent conductive electrodes. Supplied as ready-to-coat dispersions in ethanol, isopropyl alcohol, or water across a range of diameters (~23–120 nm) and lengths (10–200 µm), they enable touch panels, displays, organic and silicon solar cells, OLEDs, stretchable sensors, transparent heaters, and antimicrobial coatings.

Available grades

Choose a diameter and length to match your target sheet-resistance, transmittance, and haze. Thinner wires give lower haze and higher transmittance at a given resistance; longer wires reach percolation at lower loading. All grades ship at a standard 20 mg/ml (Agnw-X23 at 5 mg/ml) in your choice of solvent.

Key features

  • High transmittance with low sheet resistance — a percolating AgNW network conducts through sparse wires, so most of the area stays optically clear.
  • Flexible and stretchable — unlike brittle ITO, AgNW networks survive bending, folding, and stretching, enabling wearable and rollable devices.
  • Solution-processable — spin-, spray-, rod-, slot-die-coat or print directly from dispersion; no vacuum sputtering required.
  • Low-cost ITO alternative — silver is abundant and the wet process scales easily to large areas.
  • Tunable by geometry — multiple diameters and lengths let you trade off resistance, transmittance, and haze for your device.
  • Intrinsically antimicrobial — silver adds antibacterial function for coatings, films, and filtration.

Applications

Silver nanowires serve as transparent conductors and functional fillers across optics, electronics, and biomedicine:

  • Optical: solar cells, medical imaging, surface-enhanced spectroscopy (SERS), optical limiters.
  • Conductive: high-intensity LEDs, touchscreens, conductive adhesives, sensors.
  • Antimicrobial: air & water purification, bandages, films, food preservation, clothing.
  • Chemical & thermal: catalysts, pastes, conductive adhesives, polymers, chemical-vapor sensors.

Frequently asked questions

What dispersions and concentrations are available?

Silver nanowires ship as dispersions in ethanol, isopropyl alcohol, or water at a standard 20 mg/ml (Agnw-X23 at 5 mg/ml). Custom concentrations and solvents are available on request.

Which grade should I choose?

Match diameter and length to your target. Thinner wires (e.g., Agnw-X23, Agnw-40) give lower haze and higher transmittance at a given sheet resistance; longer wires (the L-series, 100–200 µm) percolate at lower loading for lower resistance. For touch panels and displays, mid-diameter L-grades are common; for low-haze optics, choose the thinnest grades.

Why use silver nanowires instead of ITO?

AgNW networks are flexible and stretchable, solution-processable without vacuum sputtering, and lower-cost at large area, while reaching comparable transmittance and sheet resistance — making them suited to flexible, foldable, and large-area devices where ITO cracks.

Can I get custom sizes or bulk quantities?

Yes. Custom diameters, lengths, concentrations, and solvents are available, and Agnw-X23 is offered for industrial-scale use. Contact us with your specifications.

What is the silver purity?

Depending on grade, silver purity is approximately 98% to 99.5%. See the grades table and the TDS for details.

How should I store and handle the dispersion?

Store sealed, away from light, and follow the SDS. Gently redisperse before use; avoid prolonged sonication, which can shorten the wires. Review the SDS for full handling and safety guidance.

Are the discontinued grades still available?

Agnw-200, Agnw-300, and Agnw-400 (200–400 nm) are discontinued. For larger-diameter requirements, contact us to discuss alternatives.

ACS Material silver nanowires are research-grade nanomaterials supplied as dispersions; values such as diameter, length, and purity are typical ranges, and real coated-film performance (sheet resistance, transmittance, haze) depends on grade, loading, substrate, and processing. Specifications are nominal and should be confirmed against the current TDS and SDS for each grade. Listed publications used ACS Material silver nanowire; they are cited for reference and do not imply endorsement. Contact ACS Material to match a grade to your application.
