Nanostructures - Soft Materials with Long Range Order

8 Nanostructures - Soft Materials with Long Range Order 

Perfection of Structure in Nanostructured Materiais. An aim of modern nanotechnology is the fabrication of materials with highly perfect structure on the nanometer scale. The distortion of such nanostructured materials can be studied by SAXS methods. Frequently the material is supplied as a very thin film with predominantly uniaxial correlation among the nanodomains. Under these constraints the nanodomains are frequently arranged in such a way that the normal to the film is a symmetry axis rotation of the film on the sample table does not change the scattering (fiber symmetry). 

SRSAXS is utilized, because the scattering curve measured in symmetrical reflection is readily transformed into a ID scattering curve, Ii ( 3). The importance of such curves for the analysis of structure has been demonstrated in the preceding sections of this chapter.
