以氯化锌为原料制备纳米氧化锌(ZnO),采用化学交联法法制备ZnO/聚乙烯醇(PVA)复合水凝胶,研究ZnO加入量对复合水凝胶拉伸强度、断裂伸长率以及溶胀性能的影响。实验结果表明:ZnO含量为0.1%时,复合水凝胶的拉伸强度和断裂伸长率最大,而ZnO含量为0.4%时,复合水凝胶的溶胀率最大。
Zinc chloride used as raw materials to prepare nano zinc oxide(ZnO),and prepared ZnO/ Poly(vinyl alcohol)(PVA) composite hydrogel by chemical cross-linking method.The ZnO amount influence on the composite hydrogel tensile strength,elongation at break and the swelling performance was studied.The experimental results show that: the content of ZnO was 0.1 %,the composite hydrogel of tensile strength and elongation at maximum,and the content of ZnO was 0.4 %,the maximum swelling ratio of the hydrogels at maximum.
