    Ball Milled Graphene Nano Additives For Enhancing Sliding

    After ball milling, the peak broadens and the height of the peak decreases. Broadening of the (002) peak is due to the disorder caused by high-energy ball-milling. The position of (002) basal plane peak also shifts to a lower angle with ball milling, resulting in an increase of interlayer spacing d 002.
