“…3, one can deduce that microemulsions of system I swelled the PDMS membrane remarkably better than those of system II; for example, a sorption of about 170% of I 1-hex was gained after 5 h and at a temperature of 25 • C, and only 35% for II 1-hex under the same working conditions. This difference in sorptions owes to the nature difference of the microemulsions of systems I and II: in I, cyclohexane has a great affinity with PDMS membrane (about 250% swelling), and in II, water has no affinity with membrane (swelling nil) [30]. That is, cyclohexane would raise the swelling ability of the microemulsion, and water would oppositely reduce it.…”

Two sets of microemulsions, cyclohexane- and water-rich ones, were prepared with the following n-alkanols as cosurfactants: n-propanol, n-butanol, n-pentanol, and n-hexanol. The results showed the influence of the alkyl chain length of the n-alkanol on the permselectivity properties of the pervaporation technique in the breakdown of the microemulsions. The variations of the total flux rate J and the enrichment factor beta were in parallel with the effect of the cosurfactant on the swelling extent of the PDMS membrane.
