Abstract: A water-based adhesive for the manufacture of laminated cellulosic boards includes monolayer graphene oxide as a glue enhancer. Laminated cellulosic boards may be obtained by providing cellulosic plies, applying a water-based adhesive, and contacting the surface of another cellulosic ply to the first cellulosic ply. A method for producing the water-based adhesive includes mixing starch, water and glue enhancer. The glue enhancer is a suspension of between 0.1 wt % and 0.001 wt % of monolayer graphene oxide in water.

Abstract: A water-based adhesive for the manufacture of laminated cellulosic boards includes monolayer graphene oxide as a glue enhancer. The adhesive includes water, starch, and at least one further polymer selected from natural and soluble synthetic polymers. The adhesive further includes a glue enhancer with monolayer oxide in water and at least one further component selected from the group including stabilizing agents, gelling agents, thickening agents, anti-foaming agents, tackifyers, and damp-proofing resins, in accordance with the polymer(s).

Abstract: The present invention is directed to a suspension and to a wet powder of reduced graphene oxide (rGO) and an organic solvent, wherein the concentration of the reduced graphene oxide in organic solvent is above 0.3 mg/mL, and wherein the mixture is stable for at least 5 days as measured in a Turbiscan™. The invention further discloses a polymer matrix comprising the rGO of said rGO suspension or wet powder and a polymer, and methods for the preparation of the rGO suspension or wet powder and the polymer matrix.

Abstract: The method consists of the formation of a layer over a stone substrate to increase its hardness, chemical resistance, wear and scratch resistance, comprising applying on the substrate a coating matrix incorporating an organic material and fillers including inorganic nanoparticles and/or microparticles; chemically binding said matrix to the substrate, by a self-assembly process and/or a binding process by covalent bonding, electrostatic bonding, van der Waals bonding or hydrogen bonds; and finally drying said matrix. The mentioned organic material is selected from organosilanes, organophosphates, polycarboxylic compounds, compounds based on triazine heterocycles and said nanoparticles are nanoparticles of oxides, carbides, borides, nitrides of metals or of semimetals.
