1. They have a high concentration of graphene flakes – up to 100g per litre.

2. They are made in a microfluidisation process, during which graphene flakes are broken off graphite using ultra-high shear forces.

3. 100% of the starting graphite material is converted into useable graphene flakes.

4. Carboxymethylcellulose sodium salt is used to stabilise the material, without a need for centrifugation.

5. Applications include large-scale screen-printing, flexible electronics, such as transistors and photovoltaic cells, and potential future uses in food packaging.
