A molecular model for the formation and properties of fluid gels

The effects of biopolymer gelation in a shear field are discussed. Gel particles are produced if the gelation mechanism involves an aggregation step. Particular attention is paid to the molecular events of ordering and aggregation upon cooling, investigating the differences in such processes as a re...

Zusammenfassung:The effects of biopolymer gelation in a shear field are discussed. Gel particles are produced if the gelation mechanism involves an aggregation step. Particular attention is paid to the molecular events of ordering and aggregation upon cooling, investigating the differences in such processes as a result of shearing during gelation. A model is proposed which follows the conception of the particles, their growth, physical properties and stability.
