Microfluidization of graphite and formulation of graphene-based conductive inks
Published 11 Nov 2016 in cond-mat.mtrl-sci and cond-mat.mes-hall | (1611.04467v1)
Abstract: We report the exfoliation of graphite in aqueous solutions under high shear rate [$\sim108s{-1}$] 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$\sim2\Omega/\square$. This is a simple and scalable production route for graphene-based conductive inks for large area printing in flexible electronics.
