NOVELTY - A composition comprises: inorganic plates with individual plate thickness of less than 10 nm, interspersed with discrete nanotubes having a diameter of 1 to 150 nm, and an aspect ratio of 10 to 500.    USE - As a composition used in a fabricated article such as a tire, industrial rubber part or wind blade; in a battery, capacitor, solar cell; in powder or liquid mixture used for catalysts or catalyst supports for gas phase reaction; in liquid or solid mixture used for catalysts or catalyst supports for solution and slurry phase reactions; in a concrete mixture used for a foundation, road, or bridge, or in a ceramic mixture used for green-ware to produce ceramic parts (all claimed).    ADVANTAGE - The carbon nanotubes can be inserted between graphene plates thus restricting their agglomeration and facilitating exfoliation in a broad range of materials including liquids and solids. Furthermore, as the plates are now separated, reactions can be entertained at the surface of the graphene plates to give, for example, oxygenated graphene structures. The diameter of the tubes can be used to control the inter plate distance. Selecting tubes of different diameters can lead to controlled transport of molecules or ions between the plates.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following    (1) a method for preparing graphene carbon nanotube composites, involving: a) suspending non-discrete graphene and non-discrete carbon nanotube fibers in an acidic solution for a time period to form a suspension; b) agitating the suspension; c) sonically treating the suspension of graphene-carbon nanotubes to form graphene-discrete carbon nanotube fibers; and d) isolating the graphene-discrete carbon nanotube fibers from the acidic solution prior to further treatment using solid/liquid separations, where the solid/liquid separations comprise filtration; and    (2) a method for preparing inorganic plate-carbon nanotube composites, involving suspending non-discrete carbon nanotube fibers in an acidic solution for a time period to form a suspension; sonically treating the suspension of carbon nanotubes to form discrete carbon nanotube fibers; isolating the discrete carbon nanotube fibers from the acidic solution; washing the discrete carbon nanotube fibers with water or another liquid; redispersing the discrete carbon nanotube fibers with inorganic plates, optionally with surfactants and sonication; optionally adding a polymer; optionally adding a transition metal complex; optionally adding an electroactive material; optionally adding a ceramic; and separating the mixture and optionally drying.
