Structure-property relationship interfacial regions

The study of the phase structure of semicrystalline polymers, particularly that of the interfacial region, is of foremost importance, since it has an intimate relationship with the macroscopic properties of polymers. Many techniques have been used to study this problem. To determine the mass fraction of each phase of the three-phase structure, such techniques as H broad-line NMR or Raman... 

As stated previously, the measurement of the surface tension of a surfactant solution is possibly one of the most common physical properties of such solutions used to characterize the properties of surfactants in general. Since the surface tension of a liquid is determined by the energy of the molecules in the interfacial region, the displacement of surface molecules by adsorbed solute will directly affect the measured value. It is the relationship between the chemical structure of an adsorbing molecule and the rate and extent of adsorption under given circumstances that differentiates the various surfactant types and determines their utility in applications where surface tension lowering is of importance.
