以三甘醇(TEG)为溶剂,高温热分解乙酰丙酮锌合成了氧化锌纳米粒子.为改善氧化锌纳米粒子表面性能和生物应用性能,分别用硅烷偶联剂(KH550)和聚酰胺-胺(PAMAM)进行表面修饰,在氧化锌纳米粒子表面接枝了-NH2活性官能团.分别采用X射线衍射仪(XRD)、透射电镜(TEM)、红外光谱(FT-IR)、X射线光电子能谱、动态光散射(DSL)和紫外可见分光光度计(UV-Vis)对样品进行了表征测试.XRD结果表明纳米氧化锌的平均晶粒尺寸为10 nm,并具有较好的结晶性.TEM观察表明,其形貌为颗粒状和小晶粒团聚成的球状粒子.FT-IR、XPS、DSL和Zeta电位测试结果表明氨基官能团成功修饰在氧化锌纳米粒子表面,增强了粒子的表面功能.UV-Vis光谱表明,氨基活性基团修饰后的纳米氧化锌仍然具有较强紫外带隙吸收.
