## Abstract Poly(vinyl alcohol) (PVA) physical hydrogels were prepared by repeated freezeโthawing cycles using aqueous solutions of two PVA samples having different degrees of syndiotacticity, aโPVA and sโPVA with 55% and 61% of syndiotactic diads, respectively. The hydrogels were prepared in the p
## Abstract To create a moist environment for rapid wound healing, a new CโPโA film with sustained antibacterial capacity had been developed by the casting/solvent evaporation method. This new type of CโPโA film consists of a chitosan top layer and sodium alginate sublayer separated by an ornidazol
