内容摘要：Thebiocompatible and highly porous keratin-based hydrogels were prepared usingelectron beam irradiation (EBI). The conditions for keratin-based hydrogelformation were investigated depending on several conditions, including thepresence of poly(vinyl alcohol) (PVA), concentration of keratin solution, EBIdose, and poly(ethylene imine) (PEI) additives. The pure keratin (human hairand wool) aqueous solution was not gelled by EBI, while the aqueous keratinsolutions blended with PVA were gelled at an EBI dose of more than 90 kGy.Furthermore, in the presence of PEI, the aqueous keratin solution blended withPVA could be gelled at a considerably lower EBI dose, even at 10 kGy. Thisfinding suggests that the PEI additives significantly influence the rate ofgelation and that PEIs function as an accelerator during gelation. Theresulting keratin-based hydrogels were characterized using scanning electronmicroscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), gelfraction, degree of swelling, gel strength, and kinetics of swelling analyses.
