About us


Graphene Inks

for product and application development

Proprietary process

Cambridge Graphene uses a scaleable production process for its graphene ink, developed at the Cambridge Graphene Centre, University of Cambridge. The process allows for a range of ink formulations to be manufactured in order to meet the requirements of different printing methods and substrates. Currently, all Cambridge Graphene inks are aqueous, environmentally friendly and non-toxic.

Custom Inks

As well as standard inks, Cambridge Graphene can customise its ink formulations to meet the requirements of its customers. Tailored inks for different substrate choices, printing method and product performance are all possible. Let us know your requirements.

What we do


We supply proprietary Graphene inks and develop proprietary IP in products and scaled-up processes for licensing. We undertake development projects for customers in application areas including, but not limited to:

High performance inks for conductive applications

Printed conductive inks for flexible electronics, antennas and a range of new products. Graphene inks can be cheaper, flexible, printable and better for the environment than traditional circuit board solutions.

Graphene enhanced composites

Graphene has been shown to significantly modify the characteristics of composite materials. Exactly which form of graphene and functionalisation to use in specific applications is a development challenge for manufacturers. We undertake projects to define the recipe required for commercial products.

Supercapacitors and batteries

Increased processing power means increased energy usage. Graphene’s applications in battery and capacitor technology will deliver huge advances across the low-power device market.
