- *Abstract
-
A family of organic−inorganic hybrid lubricants with improved wear and stability was created from nanoparticles densely grafted with amphiphilic (soap-like) organic chains. The particles are stabilized against aggregation by covalent tethering. When thesehybrid particles are dispersed in poly-α-olefin oligomers or other base oils, they formhomogeneous nanocomposite fluids at both low and high particle loadings.
Exceptionally stable hybrid lubricants werecreated and their mechanical properties tuned--spanning the spectrumfrom simple liquids to complex gels--for suitability in a wide variety of lubricant formulations. Compared to competitive materials with nanoparticle additives, these hybridlubricants simultaneously exhibit lower interfacial friction coefficients,enhanced wear, and superior thermal stability.
Potential Applications: Lubrication waxes, greases and oils for demanding applications, e.g. high-performance machines with tight tolerancesAdvantages:
- Simple synthesis
- Wear resistance
- High stability
- Tunable particle loading for specific applications
