Preparation and Characterization of Clay/Hydrogel Composites by Various Radical Polymerization |
| 초록 |
The hydrogel was prepared with imogolite, halloysite, and laponite whose surface was activated by γ-ray irradiation to initiate gelation. The dynamic behavior of imogolite-poly(acrylic acid) nanocomposite hydrogels was investigated by dynamic light scattering (DLS), small angle X-ray scattering (SAXS) and small angle neutron scattering (SANS) to determine the effects of particle concentration and the magnitude of deformation. These measurements revealed that the imogolite network was composed of particle-overlaps. We also discuss the formation and structure of poly(n-isopropylacrylamide)-laponite hydrogel by γ-ray irradiation. γ-ray generates radicals and forms 3D networks without any cross-linker. The existence of clay cross-linker affects swelling abilities of hydrogels. The structure of swollen poly(n-isopropylacrylamide)-laponite hydrogel by γ-ray irradiation is also investigated and compared with other chemical methods. |
