Abstract :
A novel micro/nano-porous superabsorbent hydrogel was synthesized via
graft copolymerization of acrylamide (AAm) onto salep (a polysaccharide mixture) and
a gelatin (a protein) hybrid backbone, after hydrolysis of this system. The Taguchi method
was applied for the experiments, and standard 18 Orthogonal Arrays (OA), with seven
factors and three levels for each factor, were the proposed trial conditions. Considering the
results of 18 trials, according to the analysis of variance (ANOVA), optimum conditions
were suggested. In addition, swelling kinetics, swelling in various organic solvents, the
Absorbency Under Load (AUL) and On-O switching behavior were investigated. Also,
the hydrogel formation was con rmed by Fourier transform infrared spectroscopy (FTIR).
The surface morphology of the synthesized hydrogels was assessed by Scanning Electron
Microscopy (SEM) and showed a micro/nano-porous structure. Also, the surface area and
total pore volume of the optimized hydrogel were measured using the Brunauer-Emmett-
Teller (BET) technique
