Rheo-SAXS of graphene inks

Graphene has the potential to revolutionize the field of printed electronics thanks to its high conductivity, flexibility, chemical stability and natural abundance. We have previously developed conductive screen printing inks through the gelation of graphene-polymer dispersions. The gelation mechanism of these inks and the role of polymeric stabilizers therein is still poorly understood. The structure of such inks under shear will be studied with rheo-SAXS.
