Graphene in Functional Building Materials
ZnoNova Materials
Construction is where graphene marketing has been at its loosest, so this page is deliberately narrow. We supply a characterised waterborne dispersion. Below is where it plausibly helps, and the three things we are not going to claim.
The material
| Form | Waterborne acrylic dispersion, graphene 5% / resin 22.5%, dilutable |
|---|
| Layers / lateral size | 5–8 layers · 3–6 µm |
|---|
| BET | 500–700 m²/g |
|---|
| Verification | Raman D 1348.6 / G 1578.5 / 2D 2713.2 cm⁻¹, SEM supplied |

| Compliance / packaging | RoHS · 1 kg bottle or 20 kg drum |

Where it plausibly helps
Barrier in protective coatingsThe tortuous-path mechanism is geometric and real, which is why
anticorrosion is the best-founded construction-adjacent use.
Antistatic and conductive floorsWhere a black finish is acceptable and a conductive network is wanted without humidity dependence.
Thermal spreading layersIn-plane conduction in a coating or a laminate rather than through-thickness insulation.
Functional surface treatmentsWhere the substrate can be dark and the coating is doing more than decoration.
The three claims we will not make
- We will not claim it insulates. Graphene is a conductor of heat. A graphene coating spreads heat; it does not resist its passage. Any marketing that presents graphene as thermal insulation has the physics backwards, and a specifier will know it.
- We will not quote a concrete strength increase. Graphene in cementitious systems is an active research area with real results in the literature, but dispersion in a highly alkaline, high-ionic-strength mix is the entire problem, and our product is a waterborne acrylic dispersion designed for coatings, not a cement admixture. We would be selling you the wrong product.
- We will not claim air purification or self-cleaning. Those are photocatalytic functions and belong to materials such as titania, not to graphene.
What to establish before specifying
Colour is usually the first constraint, because the dispersion is black. Then adhesion and weathering on your substrate, the add-on needed to reach a functional network if conduction is the goal, and compatibility with the rest of your coating system. We publish the material characterisation; performance of a finished coating is established by your testing, and we will not pre-empt it with a number that would not transfer.
Questions buyers ask
Does a graphene coating insulate a building?
No, and we will not say it does. Graphene conducts heat well; it spreads heat rather than blocking it. If you need insulation, this is the wrong material class.
Can we add it to concrete?
Not this product. It is a waterborne acrylic dispersion designed for coatings. Cementitious systems are a different dispersion problem and would need a different product.
What colour is it?
Black. That is usually the first thing that decides whether a construction application is viable.
How do we verify it is graphene and not graphite?
Raman spectrum, BET of 500-700 m2/g and SEM, all supplied with the sample. Graphite does not reach that surface area.
