(Before It's News)

Researchers at the Cambridge Graphene Centre at the University of Cambridge, UK, have designed a method for producing high quality conductive graphene inks with high concentrations. Conductive inks are useful for a range of applications, including printed and flexible electronics, transistors, and more.

The method uses ultrahigh shear forces in a microfluidization process to exfoliate graphene flakes from graphite. The process is said to convert 100% of the starting graphite material into usable flakes for conductive inks, avoiding the need for centrifugation and reducing the time taken to produce a usable ink. The research also describes optimization of the inks for different printing applications, as well as giving detailed insights into the fluid dynamics of graphite exfoliation.
