A method for preparing and observing clay platelets for size and shape analysis using scanning electron microscopy (SEM) was developed. Samples of the clay platelets were prepared by polyelectrolyte-assisted adsorption onto a pyrolytic graphite surface. The use of graphite as a substrate was advantageous because of the low number of secondary electrons emitted from it during imaging by SEM. The...

Direct mass exfoliation of graphene from bulk graphite with high yield and productivity for commercial applications is challenging. This work proposes self-grinding using the mutual shear friction particles to fabricate microcrystalline graphite. The concept implemented microbeads as grinding medium drive between nanocrystals in a high-concentration paste. proposed approach substantially improv...
