In order to obtain a more ideal hydrogel wound dressing, PEO graft hydrogcl films formed by electron bcam（EB） irradiation of the aqueous solutions of poly（ethylene oxide）（PEO） incorporated with poly （vinyl alcohol） （PVA） at different ratio were prepared, and their physiochemical properties were investigated as a function of production factors combination. The experimental results showed that gel fraction of the PEO graft hydrogel films depended mainly on irradiation dose and concentration of the polymers. Their degree of swelling was intimately related to irradiation dose, concentration, blending ratio and molecular weight of the polymers. Their tensile strength and elongation at break were obviously dependent on irradiation dose and blending ratio of the polymers. It is found that a new PEO E-30 graft hydrogel film of 20 wt% at a ratio of 7:3 has better physiochemical properties such as flexibility, moderate gel fraction, degree of swelling and clougation at break, especially its higher tensile strength than other PEO graft hydrogel films or pure PEO E-30 hydrogel film. These results indicated that PVA can improve the mechanical strength of the PEO E-30 hydrogel film through reducing the degree of swelling of the PEO E-30 hydrogel film after the irradiation graft.
