Abstract EN
Hydrogels with chemical sensitive switch have control release properties in special environments.
A series of polyacrylamide-octadecyl methacrylate hydrogels crosslinked by N,N′-bis (acryloyl) cystamine were synthesized as potential chemical sensitive system.
When this hydrogel encounters dithiothreitol it can change its quality.
The properties of the hydrogels were characterized by infrared spectroscopy, contact angle, and scanning electron microscopy.
The water absorption of the hydrogel has the maximum value of 475%, when the content of octadecyl methacrylate is 5 wt%.
The amount of weight loss was changed from 34.6% to 17.2%, as the content of octadecyl methacrylate increased from 3 wt% to 9.4 wt%.
At the same time, the stress of the hydrogel decreased from 67.01% to 47.61%; the strength of the hydrogel reaches to the maximum 0.367 Mpa at 7 wt% octadecyl methacrylate.
The increasing content of octadecyl methacrylate from 3 wt% to 9.4 wt% can enhance the hydrophobicity of the hydrogel; the contact angle of water to hydrogel changed from 14.10° to 19.62°.
This hydrogel has the porous structure which permits loading of oils into the gel matrix.
The functionalities of the hydrogel make it have more widely potential applications in chemical sensitive response materials.
