Ionic soft matter includes suspensions of charged colloidal particles, polyelectrolyte solutions, polyelectrolyte gels, ionic micelles, etc. A common special feature in these materials is that they consist of macro-ions (of the form of particles, polymers or micelles), which have many ions attached to them, and small ions that can move around freely. In usual electrolytes, all ions are equally mobile, while in ionic soft matter, a large fraction of ions are bound to the backbone structure and are less mobile, an asymmetry that gives special features to ionic soft matter distinctive from usual electrolytes. Compared with non-ionic matter, ionic soft matter have many more parameters for their properties to be controlled: the properties of ionic soft matter can be changed by pH and salinity. The ionic states and their dynamics can also be controlled by electric fields. This chapter discusses these distinctive features of ionic soft matter.
