摘　　要：用超重力法制备出了近球形和长条形的纳米氧化锌,用TEM,XRD,TG,紫外可见光谱仪等手段对制得的纳米氧化锌进行了表征,并将其应用于偶氮二甲酰胺(AC)的分解以及聚氯乙烯(PVC)糊树脂的发泡,分析了其作用机理,结果表明该法制备的纳米氧化锌粒径小且均匀,具有很强的紫外吸收能力。Sphere and strip nano zinc oxide were prepared by the tating packed bed (RPB) and characterized by TEM,XRD,TG and ultraviolet-visible spectrophotometer. The prepared nano zinc oxide was applied to lower AC decomposing temperature and froth PVC. The mechanisms were analyzed. It is verified that nano zinc oxide prepared by this method has narrow size distributions, smaller size and strong absorption ability for ultraviolet radiation.
