surface pressure isotherms for punicine derivatives and oleic acid/sodium oleate

Data sets of surface pressure isotherms for punicine derivatives (octyl-, nonyl-, decyl-, undecyl- and heptadecyl-punicine) and oleic acid/sodium oleate. Measurements were carried out at the Langmuir-Blodgett Minitrough of KSV Instruments Ltd. For each measurement the surfactant was solubilized in 1:1 EtOH and chloroform. This solution was placed on top of water (conductivity < 0.8 µS) and after an evaporation time of 10 min measurements were started.
