摘要：
Cross-linked hydrogels of polyethylene glycol (PEG) and carboxymethyl chitosan (CMCh) were synthesized using a blending technique. Several analysis tools were used to characterize the physical and thermal properties of CMCh/PEG hydrogels, namely, Fourier transform infrared, scanning electron microscope, X-ray diffraction, and thermogravimetric analysis. Some applications were carried out for the prepared cross-linked hydrogels; swelling behavior of the CMCh/PEG hydrogels was studied in different buffered solutions and different salt solutions. Metal ions uptake was studied for CMCh/PEG hydrogels. The biological activity of CMCh/PEG towards Escherichia coli has been examined in this study.
