Influence of n-alkyl acids on the percolative phenomena in AOT-based microemulsions

A study was carried out on the influence of the n-alkyl acid addition on the electric percolation of AOT/iso-octane/water microemulsions ([AOT] = 0.5 M and W= [H2O]/[AOT] = 22.2). The observed influence has been explained taking into account the organic nature of these molecules and, hence, their capacity of disturbing the structure of the AOT-film. For these reasons, relationships with their molecular structure (chain length) were analysed.

The influence of fatty acids on the AOT/iso-octane/water microemulsions percolation has been explained taking into account the organic nature of these additives and their capacity of disturbing the AOT-film structure.Figure optionsDownload as PowerPoint slide
