Dispergerte

Dispergerte is a German participial adjective meaning dispersed or distributed, derived from the verb dispergieren (to disperse). It is used to describe a system in which a dispersed phase exists as small particles, droplets, or bubbles within a continuous phase. The adjective commonly precedes a noun, as in dispergierte Partikel, dispergierte Phase, or dispergierte Suspension.

In science and engineering, the concept of dispersion is central to colloidal chemistry, materials science, and process engineering. Dispergierte Partikel may be solids dispersed in a liquid (a suspension) or droplets dispersed in a gas (an aerosol). In polymer science, dispergierte Nanopartikel can be embedded in a matrix to modify properties. In coatings and inks, dispersed pigments create coloration. In food science, dispersed oils or pigments are common.

Terminology: the related noun is dispersion; the verb is dispergieren. A dispersed system is often referred to as a dispergiertes System or Dispersionssystem. Dispergierte Systeme are characterized by the size distribution of the dispersed entities, the stability of the dispersion, and the interfacial interactions between phases. Stabilizers, surfactants, or polymers are commonly used to prevent coalescence or sedimentation of the dispersed phase.

The form dispergiert is the past participle used in passive constructions and as a predicate adjective, e.g., Partikel sind dispergiert. Grammatically, dispergierte is the feminine singular or plural form of the adjective, depending on the noun it modifies.
