3.4.1 DETERMINATION OF THE INTERLAYER SPACE
The X-ray determination of the interlayer distance in the initial and modified layered
silicates as well as in final polymeric nanocomposite is one of the main methods of
studying the structure of the nanocomposite on the basis of the layered silicate. The
peak in the small-angle diapason (2q = 6–8°C) is characteristic for pure clays and re-
sponds to the order of the structure of the silicate. This peak drifts to the smaller values
of the angle 2q in organo-modified clays. If clay particles are uniformly distributed
in the bulk of the polymeric matrix ...
