Modulation of physical properties of reverse hexagonal mesophases: A dielectric spectroscopy study

► Three processes of the HII mesophase are detected using dielectric spectroscopy. ► Phosphatidylcholine affects the dynamic and kinetic properties of the HII matrix. ► 10 wt.% phosphatidylcholine is the optimal concentration for structural stability. ► Triacylglycerol percolates and transfers between the HII rods.
