How to relax : Dynamics in colloid polymer composites during syneresis

Abstract

Colloids consist of nanometer to micron sized objects that form a dispersed phase when suspended in a continuum phase. Depending on the states of matter involved, we can distinguish colloidal sols, emulsions, foams, aerosols, solid suspensions, porous materials and solid foams. Manifestations of the colloidal domain surround us every day. In nature, colloidal systems are omnipresent: gas dispersed in liquid gives foam; solid and liquid dispersed in gas give smoke and fog, respectively. Many of our daily commercial products involve colloidal systems as well: production of porous plastic, paint, lubricants, home and personal care products such as shampoo, cosmetics, skin creams, toothpastes and
