I'm trying to formulate a stable dispersion of graphite in paraphinic oil. I'm using a very pure graphite with very small particle size. I've tried all kinds of surfactants and dispersants but none of them have worked so far, and at the end the graphite keeps separating.
So far I've used several surfactants
(from nonyl phenols, to phosphate esters) and ethylene/propylene copolymers. I've also used fatty acids, amines, sulphonates, and others.
Can anybody point me in the right direction? Is there some web site where I can find information on this matter?
