On the basis of the SANS results, a molecular mechanism has been recently proposed for the toughness enhancement of DN gels [34]. This mechanism rationalizes the changes in molecular structure of the DN gel constituents observed via in-situ neutron scattering measurements, the composition dependence of the solution viscosity, and the thermodynamic interaction parameters of PAMPS and PAAm molecules obtained previously from neutron scattering studies. More specifically, this proposed mechanism provides an explanation for the observed periodic compositional fluctuations in the micrometer range induced by large strain deformation.

In most cases, it appears possible to interpret the critical behavior of microemulsion mixtures as a liquid/gas-like critical point [113-116]. Several light- and neutron-scattering studies on oil-rich ternary and quaternary microemulsions have clearly demonstrated that the structure of these media can be described as a solution of interacting water-in-oil droplets. As first shown by Calje et al. [117], the droplets may behave essentially as hard spheres. However, in many systems an attractive contribution to the interactions exists. It has been established that the strength of attractions between W/0 micelles is strongly dependent on the micellar size and on the chain lengths of both the alcohol and oil molecules. In particular, attractions have been found to increase when the micellar radius increases or the alcohol chain length decreases and the molecular volume of the oil increases [114, 115, 118-120]. 

While all of them have been successfully applied to flat surfaces, in the case of zeolites only (i) and (iv) are of essential interest. Due to its significance. Chapter 4 has been devoted to neutron scattering studies. In the following we shall therefore deal essentially with experiments obtained by interaction of infrared radiation with vibrationally changing dipole moments. 

Methane is one of the best-understood adsorbates in zeolites. By the concomitant application of infrared spectroscopy, inelastic neutron scattering and theoretical studies the interaction of this molecule and its dynamic behaviour have been carefully investigated by Cohen de Lara et al. [114-122]. Chapter 4 deals in detail with neutron scattering studies on this molecule.
