Hydrophilic tension
WebSurface Tension. Surface tension is the energy, or work, required to increase the surface area of a liquid due to intermolecular forces. Since these intermolecular forces vary depending on the nature of the liquid … WebVIII.C Aggregates at Hydrophilic Surfaces. Hydrophilic surfaces, on the other hand, interact with the much smaller surfactant headgroup. It is therefore natural to expect “full” aggregate structures, whose curvature is controlled as much by intermolecular interactions as by the surface. This is exactly what is observed by AFM.
