【 摘 要 】

Dithiothreitol was employed as a responsive agent for disulfide bond in N,N'-bis (propionyl) cystamine in N,N'-bis(propionyl) cystamine - acrylamide/CNWs composite hydrogel. This hydrogel was obtained by mixing a queous solutions of CNWs, N,N'-bis(propionyl) cystamine and acrylamide at room temperature. The internal morphology, and crystalline performance of the hydrogels were characterized by scanning electronmicroscopy(SEM) and X-ray diffraction. The scanning electronmicroscopy(SEM) showed that the hydrogel has aporous structure. X-ray diffraction patterns confirmed that N,N'-bis(propionyl) cystamine - acrylamide /CNWs composite hydrogel has amorphous structure. The water swelling ratio reaches to the highest value at 0.067g/ml CNWs concentration.
