The Synthesis of a Chemical Stimuli Nanowhiskers of Cellulose (CNWs) Composite Hydrogel

Long aspect-ratio CNWs derived from non-toxicity, sustainable, biocompatibility cellulose has high mechanical properties and often be applicated as strengthening agents in composites and hydrogels. N, N'-bis (propionyl) cystamine and acrylamide can form chemical stimuli hydrogel through copolymerization in water solution. Disulfide bond in N, N'-bis (propionyl) cystamine may perform link/ break transition in response to chemical stimuli. CNWs were performed as reinforce agent of acrylamide- N, N'-bis (propionyl) cystamine hydrogel. A series of CNWs composite hydrogels were prepared by acrylamide, N, N'-bis (propionyl) cystamine solution with CNWs suspensions homogeneously dispersed. The structure of the composite hydrogel was characterized by fourier transform infrared spectroscopy (FTIR).
