In this study, water soluble carboxymethyl chitosan (CM-CS) and poly(vinylpyrrolidone) (PVP K-90) scaffolds were crosslinked by an irradiation technique. The optimization of scaffolds was performed for compositions of CM-CS (2.5 g, 3.5 g, 4.5 g) and PVP K-90 (6.5 g, 5.5 g, 4.5 g) as well as based on variation of electron beam doses 15 kGy (set 1), 30 kGy (set 2), and 45 kGy (set 3). The prepared scaffolds were analyzed using Fourier transform infrared (FTIR) spectroscopy, swelling analysis, gel content (%), and thermal gravimetric analysis (TGA). |
