Device for exfoliation of plate-shaped materials comprising microchannels

The present invention relates to a separation apparatus of the plate material to peel off the graphite, the release device of the sheet material according to the invention while using a particular micro-channels applying the shear force required for the graphite delamination, while graphene is not itself a grinding So it does also has a feature that can increase the production efficiency of graphene dispersion by a pin discharge flow rate increases.
