Researchers develop 3D graphene-derived blocks for improved conductive inks

The team addressed this challenge by compacting expanded reduced graphite oxide into dense-block reduced graphite oxide, termed DB-rGtO, allowing the formulation of stable dispersions of graphene-derived material at concentrations up to 200 mg·mL−1, while maintaining manageable flowability and deformation resistance.

Researchers from Monash University and Swansea University recently reported a new way to create highly concentrated graphene inks that flow well enough for industrial printing, without relying on performance-limiting additives.The team addressed this challenge by compacting expanded reduced graphite oxide into dense-block reduced graphite oxide, termed DB-rGtO, allowing the formulation of stable dispersions of graphene-derived material at concentrations up to 200 mg·mL−1, while maintaining manageable flowability and deformation resistance.
