The present invention provides a swash plate, for a swash plate compressor, which is excellent in a resistance to the occurrence of seizing in a condition where an extreme pressure is generated owing to local contact between the swash plate and a shoe which slides thereon and in a condition where lubricating oil is depleted, capable of preventing cavitation-caused erosion of a resin film when the swash plate is operated at a high surface pressure and a high speed in the presence of the lubricating oil and the swash plate compressor having the swash plate. A swash plate ( 3 ) for a swash plate compressor is so constructed that inside a housing ( 1 ) where a refrigerant is present, the refrigerant is compressed and expanded by converting a rotational motion of the swash plate ( 3 ) mounted perpendicularly and obliquely on a rotational shaft ( 2 ) by directly fixing the swash plate ( 3 ) to the rotational shaft ( 2 ) or indirectly fixing the swash plate ( 3 ) to the rotational shaft ( 2 ) through a coupling member into a reciprocating motion of a piston ( 5 ) through a shoe ( 4 ) which slides on the swash plate ( 3 ) into a reciprocating motion of a piston ( 5 ) through a shoe ( 4 ) which slides on the swash plate ( 3 ). A resin film containing 25 to 70 parts by weight of fluororesin and 1 to 20 parts by weight of graphite for 100 parts by weight of matrix resin and having a tensile shear adhesive strength not less than 25 MPa is formed on a sliding contact surface of the swash plate ( 3 ) on which the shoe ( 4 ) slides.

Disclosed herein are star-shaped macromolecular structures comprising a hyper-branched silicon containing core grafted with a well-defined and controllable number of alkyl (methyl)acrylate (co)polymer arms. The presence of the robust inorganic core provides additional resilience against mechanical degradation and therefore enhanced additive life time. Control over the additive architecture was complemented by tunability of the length of the grafted polymers by making use of controlled radical based polymerization techniques. The performance of these novel inorganic-organic star-shaped hybrids were compared to traditional fully organic lubricant additives. Detailed analysis revealed the multi-functional character of the hybrids by simultaneously performing as bulk viscosity modifiers, boundary lubricant, and wear protectants while being dispersed in a commercially available base oil for automotive lubrication purposes. 1. A composition of matter , comprising:A star-shaped polymer comprising polymer chains grafted to or from a densely cross-linked silicon-containing hyperbranched core, wherein the densely cross-linked silicon-containing hyperbranched core comprises a silicate functionalized with one or more organic groups.2.

A solid-state lubricant composition is disclosed. The solid-lubricant contains graphene, an oxide of a metal, and one or more polymeric binders. A method of making a solid-state lubricant coating on various substrates is disclosed. The method includes the steps of making a homogeneous slurry comprising powder of an oxide of a metal, graphene, and a polymeric binder with organic volatile solvent; coating a substrate with the homogeneous slurry with desired thicknesses; and drying the slurry on the substrate naturally or applying additional heat, resulting in a solid lubricant coating on the substrate. Substrates with coated solid composite lubricant show wear reduction and lower coefficient of friction compared with uncoated substrates.
