Small-angle X-ray scattering is a method to measure scattered X-ray interference by the spatial scattering length density fluctuation in the sample. One can investigate, for example, the radius of gyration of polymer in solution, size and shape of a protein in aqueous solution, the structure of micelle (size and shape, its distribution), microphase separated structure (period and morphology), crystal lamella, the network structure of gels, nanoparticles. SAXS is a non-destructive method for observing the nanometer-scale structure and is suited for various in-situ measurements. Here, the principle of small-angle X-ray scattering is introduced, and a few examples of SAXS experiments related to the rubber materials will be given.
