Abstract PVA-alginate-Ca is of good elasticity,better flexibility and high water content.Based on water content,the preparation of PVA-alginate-Ca was optimized by experiment.The optimum preparation conditions were selected: the glutaraldehyde concentration was 0.85%,the ratio of PVA to NaAlg was 10∶1 and CaCl_2 concentration was 2.0%.Comparison of characteristics among PVA,alginate-Ca and PVA-alginate-Ca shows that the water content,tensile strength and elasticity of PVA-alginate-Ca are the highest.
