Phase diagrams of monolayers of the long chain fatty acids


  • This work was partly financed by the Bundesministerium für Forschung und Technologic as part of the Ultrathin Polymer Film Project No. 03M4008C 3. The authors would like to thank Christine Böhm for performing some preliminary experiments and Dr. G. Brezesinski for useful discussions. Special thanks are due to Professor H. Möhwald for having initiated the project, and for his continued encouragement and support.


The characteristics of langmuir-blodgett (LB) films depend on the phase of the water-surface monolayer from which they have been depoisted. A range of long-chain fatty acids have been studied and it is reported, for example, that there are a multiplicity of phases in these materials, a finding which is not in accord with currently held views.
