Abstract
This invention provides a safe, environmentally friendly and solvent free method for dispersing graphene into polymeric compositions. In this process solid particles of graphene in a fatty acid matrix are mixed into the polymeric composition. The use of these solid graphene containing particles does not create dust while being mixed into the polymer and can much more easily be mixed into the polymer. Since fatty acids, such as stearic acid, palmitic acid, and oleic acid, are frequently incorporated into the polymeric formulations used in making a wide variety of products, this technique also offers a good method for introducing the fatty acid into the polymeric formulation. In such fatty acid containing polymeric formulations this technique also offers the advantage of not introducing unwanted solvents or agents into the formulation.
