COMPOSITE PARTICLES AND METHOD OF FORMING

摘要

Composite particles and a method of forming composite particles are described. The composite particles comprise at least one inorganic nanoparticle covalently bound to at least one inorganic microparticle with a linking compound. Lubricant compositions and sprayable dispersion compositions comprising composite particles are also described.

1. A composite particle comprising:
at least one inorganic microparticle; at least one inorganic nanoparticle; and a linking compound covalently bonding said nanoparticle to said microparticle, the linking compound of the formula:
Si(Z)n(R)m wherein each Z is independently selected from the group consisting of —OR′ and —X; wherein R′ is C1-C6 selected from linear, branched, and cyclic groups, or combinations thereof and optionally which may be substituted, and each X is a halide; each R is C1-C18 selected from linear, branched, and cyclic groups, or combinations thereof, or which may be substituted; n is 0 or 1; and m is 1 or 2.
