Abstract:

An adhesive composition described herein comprises an aqueous solvent; and a population of first nanoparticles dispersed in the aqueous solvent, the first nanoparticles comprising a negative or positive charge, and an average size in three dimensions of 1 nm to 1000 nm. In some embodiments, a population of second nanoparticles is dispersed in the aqueous solvent, the second nanoparticles comprises a negative or positive charge opposite the charge of the population of first nanoparticles. In some embodiments, the population of first nanoparticles comprise an average first size in three dimensions, and the population of second nanoparticles comprise an average second size in three dimensions that is different from the average first size of the first nanoparticles.

Abstract:

A method for improving wear control in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition that includes a lubricating oil base stock as a major component; and at least one phosphazene represented by the formulaas a minor component. In the above formula, Q is nitrogen, sulfur or oxygen; a is a value from about 2 to about 6, c is a value from about 2 to about 6, e is a value from about 2 to about 6, g is a value from about 2 to about 6, i is a value from about 2 to about 6, and k is a value from about 2 to about 6; b is a value of 2a+q, d is a value of 2c+r, f is a value of 2e+s, h is a value of 2g+t, j is a value of 2i+u, and l is a value of 2k+v; q, r, s, t, u and v are independently a value of 0 or −2; with the proviso that not all of a, c, e, g, i and k are the same value. A lubricating oil having a composition that includes a lubricating oil base stock as a major component; and at least one phosphazene represented by the above formula as a minor component. The lubricating oil is useful in internal combustion engines.
