Small angle scattering study on static and dynamic behaviors of catechol modified hyaluronic acid hydrogels |
| 초록 |
This study explores the internal structure of catechol modified hyaluronic acid hydrogels, which exhibit phase controllable characteristics, by using small angle scattering measurements. We performed two types of scattering measurements upon spatial and time correlations in order to know how to distinguish the micro-phases that provide specific scattering peaks or typical polymer fluctuations. The hyaluronic acid gels were subjected to small angle X-ray scattering, neutron scattering and X-ray photon correlation spectroscopy. The results reveal the hydrogel structure that is described with static and dynamic behaviors of networks. We discuss the scattering features with the contributions of thermal polymer concentration fluctuations and long-range inhomogeneites in gel networks. The study suggests that the complementary uses of static and dynamic scattering can enhance the understanding of polymer gel systems. |
