In recent years, among the varieties kinds of biomedical material, hydrogels have attracted much research
interest as biomaterials such as contact lenses and wound dressings. Since the pioneering work of Wichterle and Lim
on crosslinked poly (2-hydroxyethyl methacrylate) (polyHEMA) hydrogels [1], and because of their hydrophilicity
and biocompatibility.
For example, both natural and synthetic hydrogels have been of interest for use as wound dressings for second
degree burns. In addition, their unique interesting properties which can meet the essential requirements of ideal
