  • Publication number: 20120142814
    Abstract: A hydrophobic coating has been made for use on interior pipe surfaces, exterior boat surfaces, and in many other applications, to reduce drag in fluid flow, thus providing an energy savings. The coating utilizes a blend of organic and/or inorganic polymers with hydrophobic nanoparticles of fumed silica and/or titania in a solvent. The coating solves the problem of poor resistance to UV light and/or abrasion found in previous coatings of similar nature. The coating of the present invention can be made to be translucent and nearly transparent whereas previous coatings of comparable hydrophobicity have all been white or opaque. The coating can be applied in a single application by an easy spraying method and the super hydrophobic property can be achieved by drying the film at room temperature for 5 to 10 minutes. A preferred coating has good resistance to UV light and some resistance to abrasion.

  • Patent number: 7926617
    Abstract: A method and apparatus for changing engine motor oil more quickly and simply than previously existing methods. To change oil on a gasoline or diesel engine, the conventional oil filter is removed and an adapter is screwed in its place. An inlet oil port of the adapter connects with the oil filter inlet line and an outlet port of the adapter connects to the oil filter outlet line. The adapter top is sealed with a recessed O-ring extending around the periphery so that oil can be pumped through the adapter into and out of the engine without leaking. The adapter inlet and outlet ports are connected by hoses/tubes to an external container with its own internal piston. The engine is turned on to idle and the engine oil pump pumps used oil from the oil pan out through the adapter outlet port into the external container.

  • Publication number: 20100022422
    Abstract: A process for producing a nanographite dispersion in a fluid wherein the thermal conductivity of the dispersion is enhanced from the base fluid by more than 10% for a 1% graphite dispersion. A high purity graphite with high crystallinity and reduced surface damage and oxidation is selected as the starting material. The starting material is subjected to a process of wet media milling in the presence of dispersant and solvent fluid. The mill temperature is controlled to control and reduce surface damage to yield a nanographite with flake shape and controlled aspect ratio until a particle size average of 300 nm diameter and 50 nm is obtained. The process recycles a portion of the milled material to increase the ratio of small particle distribution to large particles in an intermediate product with small and large particle bi-modal distribution. The large particle distribution is removed by a separation process such as centrifugation or filtration.

  • Publication number: 20090131289
    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.

  • Publication number: 20090018249
    Abstract: A hydrophobic self cleaning coating composition that can be applied by conventional methods such as by spraying the composition onto a surface forming creating a wet and dry dirt repellent coating on the surface.

  • Patent number: 7449432
    Abstract: The present invention relates to 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 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.
