Microfluidization of Graphite and Formulation of Graphene-Based Conductive Inks

摘要

We report the exfoliation of graphite in aqueous solutions under high shear rate similar to 10(8) S-1 turbulent flow conditions, with a 100 exfoliation yield. The material is stabilized without centrifugation at concentrations up to 100 g/L using carboxymethylcellulose sodium salt to formulate conductive printable inks. The sheet resistance of blade coated films is below similar to 2 Omega/square. This is a simple and scalable production route for conductive inks for large-area printing in flexible electronics.
