(2D Materials Magazine)- Researchers from the University of Cambridge have developed a fast and cost effective method to print graphene onto substrates for potential application in printed electronics, disposable sensors and smart packaging.
The novel method involves the printing of graphene inks using a traditional roll-to-roll printing method. Graphene and other electrically conducting materials were added into traditional water-based inks and printed with the aid of standard commercial equipment.
Graphene ink manufacturing method
The researchers claim to be the the first to bring graphene inks close to real-world manufacturing and on a greater scale on commercial graphene producers. The technique developed by Hasan et al. involves suspending very small graphene particles in a ‘carrier’ solvent mixture. This is then mixed into a conductive water-based ink solution. The properties of the liquid can be controlled by modifying the ratio of the components; allowing the carrier solvent to be easily blended into a traditional conductive water-based ink.
