Summary:
The geometry of calcium carbonate (CaCO3)/polymer hybrid crystals was investigated by means of the contrast variation small angle neutron scattering. Our sophisticated contrast variation method led to decomposition of the measured scattering intensities into partial scattering functions of each component. These decomposed partial scattering functions gave detailed information on each component in the hybrid particle. Especially, on the basis of the Babinet principle (or incompressibility hypothesis), the comparison of the cross terms led to the relationships of each scattering amplitude. In this way, we could determine the geometry of the hybrid crystals in detail.
