제목 Small angle scattering study on deformed nanocomposite hydrogel
초록 In last decade, the abundant nanocomposite materials have developed to confer the high performed mechanical properties. The internal structure of deformed nanocomposite gel informs the role of nanoparticles to contribute to the mechanical property. In this research, imogolite-acrylic acid hydrogel was prepared by gamma-ray irradiation, and it 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 was 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.
