The present disclosure relates to a color-changing adhesive composition, for example, a color-changing adhesive composition suitable in the preparation of composite materials. The present disclosure also relates to methods of preparing composite materials using color-changing adhesive compositions and to composite-materials comprising such color-changing compositions.

Color-changing adhesive composition

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.

Composite particles and method of forming

The present disclosure describes compositions and a method for forming such compositions. More specifically, inorganic microparticles and surface modified silica nanoparticles are mixed to form a composition. The surface modified silica nanoparticles are present in the composition in an amount sufficient to decrease the coefficient of friction relative to a comparable composition that is free of surface modified silica nanoparticles.

Lubricant composition and method of forming

An aerosol is described comprising a composition comprising an acrylic block copolymer, a solvent, and a propellant. An article is described comprising the aerosol contained within a pressurized containment vessel comprising a valve. An aerosol mist is also described comprising droplets of an adhesive composition, wherein the adhesive composition comprises an acrylic block copolymer, a glass transition temperature modifier, and optionally an additive.
