The structure of clay dispersion in water was an assembly of clay platelets 300 A in diameter and 10 A thick. The structure factors of the clay dispersions were reduced to a master curve by normalizing with the clay concentration, Cclay, even across its sol−gel transition. On the other hand, the structure factors of the NC gels cannot be represented with a simple addition of the structure factors of the components, but with a sum of Lorentz (L) and squared-Lorentz (SL) functions. It was found that the SL term, indicating the gel inhomogeneities, becomes dominant by increasing Cclay. The chain dynamics of the gels was found to be similar to the conventional PNIPA gels chemically cross-linked with bis-acrylamide."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699996077411074","@type":"Researcher","foaf:name":[{"@value":"Mitsuhiro Shibayama"}],"jpcoar:affiliationName":[{"@value":"Neutron
