The present invention relates to a process for preparing graphene oxide which comprises subjecting an aqueous dispersion of a graphite to an exfoliation step by high shear mixing at a mixing speed equal to or greater than 3000 rpm and to an oxidation step with an oxidizing agent selected from hydrogen peroxide, potassium hydroxide and mixtures thereof, wherein the graphite exfoliation step can precede, follow or be conducted together with the oxidation step. The invention also relates to the use of the graphene oxide thus obtained to impart antimicrobial properties to rubber articles.

Abstract

The present invention relates to a process for preparing graphene oxide which comprises subjecting an aqueous dispersion of a graphite to an exfoliation step by high shear mixing at a mixing speed equal to or greater than 3000 rpm and to an oxidation step with an oxidizing agent selected from hydrogen peroxide, potassium hydroxide and mixtures thereof, wherein the graphite exfoliation step can precede, follow or be conducted together with the oxidation step. The invention also relates to the use of the graphene oxide thus obtained to impart antimicrobial properties to rubber articles.
