Abstract
Concentrated dispersion from 5 to 50% by weight of nanoparticles of graphene in water with a lateral size from 10 to 5000 nm and thickness from 0.34 to 30 nm. The production process comprises the dispersion in water of flakes of expanded graphite and the subsequent treatment with ultrasounds at an energy level of from 100 to 2000 W for a period from 1 to 100 hours.
