Emulsion rheology

Emulsions are used and prepared mainly using mechanical techniques. Recently, progress has been made in the characterisation and preparation of polymer/polymer emulsions and in emulsions with a viscoelastic continuous phase. Emulsions made from classical solvents of low viscosities can be studied using the Princen model in the concentrated regime. The role of surfactant motions, however, on the rheology of emulsions is very complex and is still not well understood.
