The mechanical measurements indicated that the number of poly(N-isopropylacrylamide) (PNIPA) chains bridging clay platelets, Nchain, per unit volume increased with Cclay4/3. Two-dimensional SANS intensity patterns exhibited the so-called “abnormal-butterfly” pattern. However, both sector-averaged scattering intensities parallel and perpendicular to the stretching direction were well represented by Ornstein−Zernike (OZ) scattering functions, suggesting that the NC gels have very little cross-linking inhomogeneities regardless of Cclay and of λ (λ ≤ 2.0). The correlation length, ξ, obtained by the OZ functions was a decreasing function of Cclay, i.e., ξ ∼ Cclay-1/3, and was in proportion to the inter-platelet distance (∼Cclay-1/3). This suggests that the c..."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380011143592681730","@type":"Researcher","foaf:name":[{"@value":"Sho
