Definition of soft matter in English:

soft matter


  • Condensed or semi-fluid matter that is easily deformed by relatively small external forces and thermal fluctuations, typically having constituent particles that exhibit Brownian motion and are capable of forming complex internal structures without external influence; also called soft condensed matter.

    A wide variety of different kinds of substance are classed as soft matter, including colloidal suspensions, surfactants, and polymers. Some common, everyday examples (of which there are many) are ice cream, paint, and milk.
