Fabrication and Characterization of Gelatin/Chitosan Hydrogel Membranes

The gelatin/chitosan (GEL/CTS, GC) membranes have been fabricated well by a simple in-situ method. as-prepared GC were characterized morphological surface (scanning electron microscopy, SEM), chemical (Fourier-transform infrared spectroscopy, FT-IR), crystallinity (X-ray diffraction, XRD), thermal (thermal gravimetric analysis, TGA), mechanical (tensile test), hydrophilic (water contact angle), and swelling properties to elucidate the changes in their structures morphologies. structure of was found be very smooth, non-rough homogeneous. FT-IR XRD studies manifest that good interaction compatibility between GEL CTS hydrogel mixture. prepared also obtain better thermal, comparing raw molecule. These results suggest nontoxic membrane can become preferred field wound dressing or tissue-engineering applications.
