Researchers from Korea's Advanced Institute of Science and Dankook University developed a new fabrication process for foldable graphene circuits based on paper substrates. The new method uses a transfer printing process to prevent direct contact of the solvent and paper and to easily control the thickness of the deposited graphene.
The researchers say that this new process is better than ink-jet printing in some regards - it enables easy control of the circuit width, there's no need for a specialized mask for complexly patterned circuits and simple modification. They say that the thickness of the circuits can be adjusted just by varying the amount of the graphene dispersion introduced for vacuum filtration.
