Modern Trends of Colloid Science in Chemistry and Biology: International Symposium on Colloid & Surface Science, 1984 held from, October 17–18, 1984 at Interlaken, Switzerland (German Edition)

Colloids are dispersions with particles corresponding to a molecular weight of at least 1000, but small enough to pass through filter paper and to show little sedimentation. There are two categories. Lyophilic colloids form spontaneously from the ingredients and they are thermodynamically stable. Lyophobic colloids have to be prepared in a roundabout way. They have to be protected against irreversible aggregation by a protective layer around each particle. Lyophilic particles are formed by chemical reaction (e.g. by polymerization) or reversible association (as with soap micelies) . Some are biocatalysts, some show rubber elasticity and many can serve as protective agents for lyophobic colloids. They can be destroyed by chemical degradation, but from a physical point of view they may live eternally. Lyophobic particles are formed by irreversible condensation, or by comminution. Monosized particles can be prepared. Most of their applications are based on the possibility to mix incompatibles, such as oil in water or insoluble substances in a solvent. They find many technical applications in paints, inks, magnetic tapes, photographie films and in the kitehen. They are destroyed by irreversible agglomeration if the pro-1 55 1 1 24 1 1 2 2.43 0.
