| 内容記述 | The anisotropic gels of poly(N-isopropylacrylamide) hybridized with liquid crystalline clay nanosheets, which show improved mechanical strength and anisotropy, were synthesized by γ-ray-induced polymerization and cross-linking. The aqueous mixtures of the monomer and liquid crystalline nanosheets were irradiated with γ rays from 60Co radiation source to synthesize the gels. In the gels synthesized in a glass capillary, the nanosheets were aligned macroscopically along the long axis of the glass capillary as revealed by polarized light microscope observation and small angle X-ray scattering measurement. The gel also showed anisotropy in thermo-responsive volume phase transition. The mechanical property of the gel was tunable by changing the nanosheet concentration and radiation dose. The elasticity of the gel was 18 kPa at maximum and this value is about 4.7 times higher than the gels synthesized by using a chemical cross-linker. Some of the gels with added clay mineral does not collapse even at 90% strain, indicating the high compressive strength. | |||||
