The present disclosure describes a strategy to create self-healing, slippery self-lubricating polymers. Lubricating liquids with affinities to polymers can be utilized to get absorbed within the polymer and form a lubricant layer (of the lubricating liquid) on the polymer. The lubricant layer can repel a wide range of materials, including simple and complex fluids (water, hydrocarbons, crude oil and bodily fluids), restore liquid-repellency after physical damage, and resist ice, microorganisms and insects adhesion. Some exemplary applications where self-lubricating polymers will be useful include energy-efficient, friction-reduction fluid handling and transportation, medical devices, anti-icing, optical sensing, and as self-cleaning, and anti-fouling materials operating in extreme environments.

Materials as additives for advanced lubrication

Номер: US9441178B2

Автор: Ali Erdemir, Kuldeep MISTRY, Michael M. Thackeray, Vilas G. Pol

Принадлежит: UChicago Argonne LLC

This invention relates to carbon-based materials as anti-friction and anti-wear additives for advanced lubrication purposes. The materials comprise carbon nanotubes suspended in a liquid hydrocarbon carrier. Optionally, the compositions further comprise a surfactant (e.g., to aid in dispersion of the carbon particles). Specifically, the novel lubricants have the ability to significantly lower friction and wear, which translates into improved fuel economies and longer durability of mechanical devices and engines.

Process for making saturated hydrocarbons and the use thereof

Номер: US8957266B2

Автор: David Lawrence Stern, Kun Wang, Margaret May-Som Wu

Принадлежит: ExxonMobil Research and Engineering Co

Provided are processes for making one or more unsaturated oligomeric acids and one or more saturated hydrocarbons. In one form, a process for making one or more saturated hydrocarbons includes oligomerizing one or more unsaturated carboxylic acids having from 4 to 38 carbon atoms in the presence of a molecular sieve catalyst to form one or more unsaturated oligomeric acids including less than 90% by weight of cyclic oligomers, and hydrogenating the one or more unsaturated oligomeric acids via contact with hydrogen in the presence of a hydrogenation catalyst to form one or more saturated hydrocarbons. The oligomerizing of unsaturated fatty acids is from renewable biological sources to form dimer acids. The one or more saturated hydrocarbons are useful as lubricant base oils.

Nanoparticle graphite-based minimum quantity lubrication method and composition

Номер: US9080122B2

Автор: Lawrence T. Drzal, Patrick Kwon

Принадлежит: Michigan State University MSU

A lubricant composition is disclosed that includes (a) a machining oil and (b) an exfoliated graphite nanoparticle (EGN) material stably dispersed in the machining oil. The lubricant composition is a stable suspension and is suitable for use as a liquid lubricant in a Minimum Quantity Lubrication (MQL) process. In the MQL process, the lubricant composition is applied/transferred to a worksite in the form of a mist. The presence of the EGN material in the lubricant composition provides high-temperature stability and lubricity under MQL conditions. A very small amount is transferred especially at high cutting speeds where the mist of the machining oil evaporates, but the EGN material remains on the surface to provide lubricity. Any operation involving machining can benefit from this lubricant composition. The method provides important benefits of reducing chipping on cutting tools and providing the additional lubricity especially when the cutting become very hot and thus extending tool life.

Provided is a method for preparing a grease composition, which comprises mixing grease components under high pressure and high flow rate impingement. In one embodiment, a first mixture of an amine in a lubricating base oil is mixed with an isocyanate in a lubricating base oil under high pressure and high flow impingement. In another embodiment, the mixing and reaction occurs in a reaction injection molding device. The orifice size through which each of the mixtures is introduced into a reaction/mixing zone is less than 0.030 inch (0.0762 centimeter) in diameter. The resulting grease composition is an extremely low noise grease, being virtually clear of any urea thickener particles, and/or can exhibit good high temperature resistance and mechanical stability.
