2 materials1 process step
Binder-free graphene nanoflake ink was printed on conventional paper substrate. The graphene-based conductive ink composition included graphene flakes, other carbon or metallic conductive fillers, dispersants, and solvents. The composition was dried at 100°C for 10 minutes. A rolling compression procedure was then applied using a compression roller to obtain a highly flexible and conductive printed graphene laminate.
Layer stacks claimed or described, ordered top of device to substrate.
