| Research Abstract |
In this study, we have tried to give anisotropy on the swelling-shrinking behavior of the hydrogel by ordering the molecular axis of cross-linker using photo-responsible azobenzene structure. We have introduced binding functional groups in the both sides of azobenzene molecule having photo aligning property. These azobenzene cross-linkers shows photo-orientation and light cure ability in solid polymers. And, the mobility of azobenzene molecules was limited by photo curing in a solid polymer matrix. Although, the influence of limitation of the cross-linker on the swelling-shrinking behavior was insignificant due to the larger disordering of polymer network caused by expansion of network at swelling behavior.
