I did an experiment of making functionalized graphene oxide and dried it in a vacuum oven after centrifugation, and ground f-GO using mortar and pestle.
But, after grinding, it still didn't become find particles.
I want to make nanocomposites (Polymer/GO & Polymer/f-GO) and compare their properties, so I think, it is important to get find particles of f-GO using mortar and pestle..
How long do I have to grind f-GO using agate mortar and pestle to get a good powder form?
Thank you.
