Abstract: A lubricant composition having an enhanced thermal conductivity, up to 80% greater than its conventional analogues, and methods of preparation for these fluids are identified. One preferred composition contains a base oil, nanomaterial, and a dispersing agent or surfactant for the purpose of stabilizing the nanomaterial. One preferred nanomaterial is a high thermal conductivity graphite, exceeding 80W/m-K in thermal conductivity. The graphite is ground, milled, or naturally prepared to obtain a mean particle size less than 500 nm (nanometer) in diameter, and preferably less than 100 nm, and most preferably less than 50 nm. The graphite is dispersed in the fluid by one or more of various methods, including ultrasonication, milling, and chemical dispersion. Carbon nanostructures such as nanotubes, nanofibrils, and nanoparticles are another type of graphitic structure useful in the present invention. Other high thermal conductivity carbon materials are also acceptable. To confer long-term stability, the use of one or more chemical dispersants or surfactants is useful. The thermal conductivity enhancement, compared to the fluid without graphite, is proportional to the amount of nanomaterials added. The graphite nanomaterials contribute to the overall fluid viscosity, partly or completely eliminating the need for viscosity index improvers and providing a very high viscosity index. Particle size and dispersing chemistry is controlled to get the desired combination of viscosity and thermal conductivity increase from the base oil while controlling the amount of temporary viscosity loss in shear fields. The resulting fluids have unique properties due to the high thermal conductivity and high viscosity index of the suspended particles, as well as their small size.

Abstract: A novel use of nanomaterials as a viscosity modifier and thermal conductivity improver for gear oil and other lubricating oil compositions. The gear oils of the instant invention have a higher viscosity index, higher shear stability, and improved thermal conductivity compared to currently available conventional gear oils. The preferred nanoparticles also impart a reduction in the coefficient of friction, including reduced friction in the boundary lubrication regime. These properties are obtained by replacing part or all of the polymer thickener or viscosity index improver or some other part of the composition normally used in gear oils with nanomaterials of suitable shape, size, and composition.

Abstract: A motor oil performance-enhancing engine treatment oil additive formulated for addition to conventional motor oil to improve the lubricating properties of the engine oil and enhance the performance of the engine. The novel engine additive comprises a synergistic combination of chemical constituents including an oil soluble molybdenum additive, polyalphaolefin, diester, polytetrafluoroethylene, dispersant inhibitor containing zinc dithiophosphate, mineral oil base stock, viscosity index improvers, and borate ester used in combination with a conventional crankcase lubricant at about a 20 to about a 25% volume/percent. The improved performance of the engine additive in comparison with conventional crankcase lubricants is attributable to the synergistic effect of optimizing the design parameters for each of the individual chemical constituents and combining the chemical constituents according to the present invention to obtain surprisingly good results including improved: wear, oxidation resistance, viscosity stability, engine cleanliness, fuel economy, cold starting, and inhibition of acid formation. The novel engine additive formulation comprises a synergistic combination of compounds, ingredients, or components, each of which alone is insufficient to give the desired properties, but when used in concert give outstanding lubricating properties. Of course, it is contemplated that additional components may be added to the engine additive formulation to enhance specific properties for special applications.

Abstract: This invention relates generally to water resistant peelable protective and decorative clear or pigmented foam coating compositions and, more specifically, to aqueous and solvent based, polymeric coating compositions which form a protective and/or decorative coating and is removably adhered to a variety of substrates, including automotive paints, metals, glass, vinyl, plastics, concrete, natural and synthetic elastomers, and ceramics. The coatings present a three-dimensional expandable foamy coating, and can be readily peeled off from the substrate as a whole piece. The coatings may be formulated for temporary or long-term protection depending upon the application. The peelable coatings can be applied as a paint, paste, film, or expandable foam cord whereby the expansion of the foam can be controlled by the formulation and applicator.

Abstract: Fluid compositions that have enhanced thermal conductivity, up to 250% greater than their conventional analogues, and methods of preparation for these fluids are identified. The compositions contain at a minimum, a fluid media such as oil or water, and a selected effective amount of carbon nanomaterials necessary to enhance the thermal conductivity of the fluid. One of the preferred carbon nanomaterials is a high thermal conductivity graphite, exceeding that of the neat fluid to be dispersed therein in thermal conductivity, and ground, milled, or naturally prepared with mean particle size less than 500 nm, and preferably less than 200nm, and most preferably less than 100nm. The graphite is dispersed in the fluid by one or more of various methods, including ultrasonication, milling, and chemical dispersion. Carbon nanotube with graphitic structure is another preferred source of carbon nanomaterial, although other carbon nanomaterials are acceptable. To confer long term stability, the use of one or more chemical dispersants is preferred. The thermal conductivity enhancement, compared to the fluid without carbon nanomaterial, is somehow proportional to the amount of carbon nanomaterials (carbon nanotubes and/or graphite) added.

Abstract: The introduction of nanotubes in a liquid provides a means for changing the physical and/or chemical properties of the liquid. Improvements in heat transfer, electrical properties, viscosity, and lubricity can be realized upon dispersion of nanotubes in liquids; however, nanotubes behave like hydrophobic particles and tend to clump together in liquids. Methods of preparing stable dispersions of nanotubes are described and surfactants/dispersants are identified which can disperse carbon nanotubes in aqueous and petroleum liquid medium. The appropriate dispersant is chosen for the carbon nanotube and the water or oil based medium and the dispersant is dissolved into the liquid medium to form a solution. The carbon nanotube is added to the dispersant containing the solution with agitation, ultrasonication, and/or combinations thereof.

Abstract: An aqueous wheel and/or tire cleaning solution for removing the dirt from the surface of aluminum, chrome, stainless steel, painted steel, painted aluminum, clear coated aluminum, rubber, and plastic wheels and tires without scrubbing by applying the cleaning solution to the wheel and/or tire then rinsing the wheel and/or tire with water. Selected polymers include a polyvinylpyrrolidone, a poly(N-vinylimidazole), a poly(4-vinylpyridine-betaine), and/or a poly(4-vinylpyridine-N-oxide) each one of which can be used with conventional wheel cleaning components such as an acid or alkaline-based cleaning formulation to dramatically improve its cleaning power. These polymers can attach to organic and inorganic dirt particles forming a complex with them for easy removal from the wheel and/or tire during rinsing, leaving the wheel and/or tire clean without scrubbing the wheel or tire surface.
