Graphene Production Milling Graphite Particles

Grinding of nano-graphite inkjet inks for application in ...

The production of printable graphene flakes is not easy to scale up when produced by ultrasonication and purified by centrifugation. In this work, natural graphite flakes were exfoliated by wet ball milling in water supported by the addition of sodium deoxycholate as a surfactant and the dispersion was formulated for inkjet printing.

Graphene production by cracking - Royal Society

(a) Production methods of graphene. In general, the synthesis methods consist of two main categories []: bottom-up (synthesizing graphene atom by atom on a substrate) and top-down (separating already-existing graphene from its host material) method.Specifically, there are two major bottom-up methods; chemical vapour deposition (CVD) and growth on SiC, both of …
