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.

A silicone grease composition having high friction characteristics and wear characteristics is disclosed. The silicone grease composition is provided by adding a zinc salt (B) containing, at a mass ratio from 1:99 to 99:1, a zinc dialkyldithiophosphate (B1) and a zinc dialkyldithiocarbamate (B2) as an extreme-pressure additive to a silicone oil (A). A method for transmitting torque of a clutch or a torque limiter mechanism is also disclosed.

The present invention relates to compositions in the form of silicone oil emulsions intended to be applied to curing bladders as a mould-release agent during tyre production.

Disclosed are materials that possess both low adhesion and the ability to absorb water. The material passively absorbs water from the atmosphere and then expels this water upon impact with debris, to create a self-cleaning layer. The lubrication reduces friction and surface adhesion of the debris (such as an insect), which may then slide off the surface. The invention provides a material comprising a continuous matrix including a polymer having a low surface energy (less than 50 mJ/m.sup.2) and a plurality of inclusions, dispersed within the matrix, each comprising a hygroscopic material. The continuous matrix and the inclusions form a lubricating surface layer in the presence of humidity. The material optionally contains porous nanostructures that inject water back onto the surface after an impact, absorbing water under pressure and then releasing water when the pressure is removed. The material may be a coating or a surface, for example.
