采用碱刻蚀法制备氧化锌(ZnO)，考察柠檬酸钠及氨水加入顺序对 ZnO 形貌的影响，并通过共混法将ZnO引入聚丙烯酸酯乳液中，研究ZnO 对聚丙烯酸酯乳胶膜透水汽性、耐水性和力学性能等的影响.结果表明，柠檬酸钠的添加及氨水加入顺序对 ZnO 的形貌均有较大影响，可在棒状、花状、银耳状和球状间变化.其中，银耳状ZnO 对聚丙烯酸酯乳胶膜的性能提升最大，透水汽性提高了357．91％，抗张强度提高了8．89％，断裂伸长率提高了1．76％.
ZnO were synthesized by alkali etching process.The effects of addition of sodium citrate and ammonia on the morphology of ZnO were investigated.Then,polyacrylate/ZnO composite latex was obtained through blending polyaceylate and ZnO.The water vapor permeability,water resistance and mechanical property of composite films were also discussed.The results show that sodium citrate and the addition order of ammonia have a great influence on ZnO morphologies,which can be changed from rod-like,flower-like,themella-like to globular.Among them,tremella-like ZnO was the best for improving the properties of polyacrylate film,which can increase water vapor permeability,tensile strength,and elongation at break by 357.91%,8.89%,and 1.76%,respectively.
