This patent relates to a lubricating oil with added decorated graphene nanoparticles, which is called nanolubricant. This nanolubricant has automotive and industrial applications and offers as major benefits, simultaneous improvements in the thermal, rheological and tribological properties of the lubricant used as base fluid. Additionally, this nanolubricant offers a rheopectic behavior from a specific concentration, the same behavior that gives it the ability to increase its viscosity over time provided it is subjected to a constant cutting rate. Finally, the decorated graphene may include metallic, ceramic or polymeric nanoparticles, in a concentration range of 0.5% weight/weight to 2% w/w without changing the newtonian fluid behavior of the base lubricant, whereas for concentrations greater than 2% weight/weight and up to 3% weight/weight, the aforementioned rheopectic behavior will be observed.

A tribologically modified polyoxymethylene polymer composition is disclosed. The polyoxymethylene polymer composition is comprised of a polyoxymethylene polymer and at least one tribological modifier. The tribological modifier may comprise an ultra-high molecular weight silicone having a kinematic viscosity of greater than 100,000 mm.sup.2 s.sup.?1. When tested against itself, the composition of the present disclosure exhibits an extremely low dynamic coefficient of friction and produces no discernible noise over a very broad temperature range, such as from ?20? C. to 60? C.

GER fluids are improved by the addition of a polar molecule additive. By addition of a polar molecule additive, yield stresses under electric field are improved by over 50% while the current density is reduced to less than a quarter of the original GER. The reversible response time still remains the same, and the sedimentation stability is greatly enhanced. The zero field viscosity of the modified GER fluid remains the same as that of the original GER fluid without the additive. The improved GER characteristics improve general functionality as an electrical-mechanical interface, attendant with applications to car clutches, fluid brakes, and vehicle shock absorbers.

The object of the present invention is to provide a foreign substance removing lubricant composition having high foreign substance removing effects and being capable of improving the lubricating properties as compared to conventional lubricant compositions, a foreign substance removing lubricant composition applied member, and a method for using the foreign substance removing lubricant composition.
