Graphene in Glass Technology

Date: Wednesday, March 20, 2024

Graphene is being researched for glass because it is thin, nearly transparent, conductive and strong. Most of this work is still in research and development, and we are exploring where our graphene dispersions and coatings could fit.

Why graphene and glass

Glass is hard and clear but brittle, it does not conduct electricity, and it is a poor way to move heat around. Graphene is a single layer of carbon atoms that is almost invisible when spread thinly, conducts electricity and heat well, and is very strong for its weight. A thin graphene layer or a small amount of graphene in a coating could, in principle, add some of those properties to a glass surface without making it look dark. That is the reason glass is a popular research target.

Where graphene is being explored in glass

  • Transparent conductive layers: a possible alternative to indium tin oxide for touchscreens, displays, solar panels and switchable (electrochromic) windows.
  • Heated glass: thin conductive graphene layers can act as heating elements for de-fogging and de-icing.
  • Coatings for strength and scratch resistance: graphene in coatings is studied for protecting glass surfaces.
  • Thermal management: graphene layers can help spread heat across glass in devices.

How our graphene would be used

We make graphene and mix it into the liquids manufacturers already use: water, solvents, resins and oils. Graphene is sold only pre-mixed in a carrier, never as a dry powder. For glass, the relevant forms are coatings and resins that carry the graphene, applied with the processes a glass or coating maker already runs. Which carrier, how much graphene and how it is applied all depend on the glass and the coating, so each application is developed with the customer. Learn how this works in our guide to graphene dispersions.

What we can and can't claim today

We don't yet publish test data for graphene in glass, and we make no antibacterial or hygiene claims. Results depend on the glass, the coating method and the graphene grade, so every application needs testing.

Our verified results so far are in other materials, such as a 67% gain in concrete compressive strength at 5% by weight of cement in independent third-party testing in 2023, and up to 42% less wear and 26% higher weld load for a lubricant in independent testing at Univar's Houston lab (press release).

Frequently asked questions

Is graphene-coated glass a product you sell?
No. Graphene in glass is in research and development with us. We supply graphene dispersions, and any glass coating would be developed together with a partner and tested first.
Can graphene make glass conductive and still clear?
Researchers are studying thin graphene layers for exactly this, for example in touchscreens and heated windows. We have not published test data of our own for glass.
Do you sell graphene powder for glass?
No. Graphene is sold only pre-mixed in a carrier such as water, a solvent, a resin or an oil. Pricing and samples are by quote.
How do I start a glass or coating project?
Contact us with the glass type, the coating process and the property you want to improve, and we will tell you whether a test makes sense.
