Calculation of self-diffusion for a water-in-oil microemulsion model

Conference paper
Part of the Progress in Colloid & Polymer Science book series (PROGCOLLOID, volume 73)


“New Trends in Colliod Science” contains the proceedings of the foundation meeting of the European Colloid and Interface Society (ECIS), October 1–3, 1986. Representatives from the major European groups working in this field contributed to the conference. The volume contains an up-to-date account of present developments in Colloid Science. The contributions cover a wide scope of subjects, and provide encouragement that structures and transport processes in dense colloidal systems can be understood on basic principles. The main subjects are include:
  • phase diagrams of new surfactant systems

  • microemulsions and their applications

  • vesicles and bilayers

  • transport properties of colloidal systems.


The long-time self-diffusion coefficient D s is calculated to first order in the volume fraction φ for a model of a water-in-oil microemulsion. The model contains the hard-core repulsion, an attractive square-well potential due to the overlap of surfactant tails and the hydrodynamic interactions. The calculation is based on the solution of the Smoluchowski equation.
