Structural changes in anionic micelles induced by counterion complexation with a macrocyclic ligand: A neutron scattering study

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 changes in micellar aggregation number which occur in SDS and C7SS solutions when the sodium ions are complexed by the cryptand C 222 have been investigated at several concentrations of amphiphile and supporting electrolyte (NaCl). The observed micellar reorganizations are rationalized in terms of changes in head group repulsion and hydrocarbon-water contant.
