Measuring Viscosity of Graphene Conductive Inks

Applications of Graphene, also known as the wonder material, have exploded over last few years. The mechanical, electrical and thermal properties of graphene make it an ideal candidate for applications including printed electronics, the development cathodes and anodes in batteries, and PV devices. 

In this brief application note, we present viscosity measurements of cyclohexanone based graphene ink as a function of shear rate. These systems often present shear thinning behavior, making it a requirement to characterize viscosity at a shear rate range relevant for each specific application.
