Nanocomposite materials has been developed to confer high performed mechanical property, and one of the efforts is preparation of inorganic particle induced hydrogel. In this research, imogolite-acrylic acid hydrogel prepared by gamma-ray irradiation was investigated with small angle X-ray scattering (SAXS) and small angle neutron scattering (SANS) in terms of particle concentration and deformation. SAXS and SANS were performed to probe the polymer contrast matched system and the ternary system, respectively. The SAXS analysis results present polymer dominant elongation, particle orientation and elongation of inter-particle distance as structural response against the external deformation. The neutron scattering analysis also supports the elongation of internal structure through the increase in correlation length of inhomogeneity of the system according to the magnitude of deformation. |
