Reproduced with permission from ref. 41. Copyright 2014 The Royal Society of Chemistry.................................................................100 Figure 19: Overview of the outputs using a high shear mixing process for exfoliation. a) Phase diagram of rotor speed, N, versus diameter, D, for dispersions showing good exfoliation according to TEM. The region above the black line represents fully developed turbulence, that is, ReMixer >104, whereas the region above the red line represents min >104 s−1. b) Concentration of graphene produced in the Silverson shear mixer as a function of shear rate for rotors with diameters of 32, 16 and 12 mm (mixing time 1 min). All three data sets are consistent with the same minimum shear rate. Reproduced with permission from ref. 40.

Copyright 2015 The Royal Society of Chemistry. ............................102 Figure 21: Concentration of graphene after centrifugation as a function of sonication time. On the left axis is the measured absorbance per cell length, A/l, while the right axis corresponds to the concentration calculated using an absorption coefficient of 3620 mL mg-1 m-1. The upper axis shows the total energy outputted by the bath calculated using the measured power output of 23 W. Reproduced with permission from ref. 20.
