More Information
Summary:The object of the invention is a method for producing flaked graphene by intercalation and exfoliation of graphite in a liquid, with continuous stirring of the components by sonication, characterized in that oleum is used as the liquid, wherein the concentration of sulphur trioxide in sulphuric acid is 1-60%. L'objet de l'invention est un procédé de production de graphène en flocons par intercalation et exfoliation de graphite dans un liquide, avec agitation continue des composants par sonication, caractérisé en ce que l'oléum est utilisé en tant que liquide, la concentration de trioxyde de soufre dans l'acide sulfurique étant de 1 à 60 %.
