Abstract
Graphene coated hollow glass microspheres may be easily prepared by mixing Pristine Graphene Particles with hollow glass microspheres under conditions to associate the Pristine Graphene Particles on the external surface of the hollow glass microspheres by ionic interaction to form graphene coated hollow glass microspheres. Graphene coated hollow glass microspheres prepared by the methods as described herein are also provided. In an embodiment, graphene coated hollow glass microspheres comprise a graphene coating formed from Pristine Graphene Particles associated on the external surface of the hollow glass microspheres by ionic interaction.
