| Abstract: | With polyvinyl alcohol as monomer, by physical cross-linking and chemical cross-linking reac- tion of PVA hydrogel, the effect on the properties of polyvinyl alcohol by using different synthetic methods is studied. This study tests the mechanical properties, ultraviolet resistance, light transmittance and permeability of polyvinyl alcohol hydrogel, and finds out the hydrogel membrane performance better. The re search shows that polyvinyl alcohol hydrogel membrane has excellent barrier performance, the permeabili- ty coefficient of 0.8 m2/s· kPa, tensile strength 16.5 Mpa, and 99.8 % transparency. |
