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...

High-yield production of few-layer graphene flakes from graphite is important for the scalable synthesis and industrial application of graphene. However, high-yield exfoliation of graphite to form graphene sheets without using any oxidation process or super-strong acid is challenging. Here we demonstrate a solution route inspired by the lithium rechargeable battery for the high-yield (>70%) exf...

In order to study the effects of pore structure and size porous carrier material on phase transformation behavior composite change materials (CPCMs), sizes three different expanded graphites (EGs) (50, 80, 100 mesh) were studied using N2 adsorption-desorption isotherms scanning electron microscopy. Then, thermal characterization CPCMs prepared with paraffin wax EGs tested differential calorimet...

Electrodes based on carbon, i.e., expanded graphite (20%, wt.)-epoxy composite(20EG-Epoxy) and expanded graphite (20%, wt.)-polystyrene composite (20EG-PS) havebeen prepared, characterized using scanning electron microscopy (SEM) and cyclicvoltammetry (CV), and tested as anodic sensors. The electrodes exhibited good mechanicalresistance and low electrical resistances. Scan rate dependent cyclic...
