摘　　要：利用葵二酸对纳米ZnO进行有机表面修饰。采用红外光谱(IR)、热分析(TG-DTA)、X射线光电子能谱(XPS)、透射电镜(TEM)、润湿性实验、分散性实验等对表面改性前后的纳米ZnO进行表征。红外光谱、TEM及XPS表明,在纳米ZnO表面包覆有葵二酸的有机层。热分析显示,包覆量约为14.5%。润湿性及分散性实验表明,经葵二酸改性的纳米ZnO的表面性质由亲水变为疏水。The surface organic modification of nanosized ZnO was studied. The prepared samples were characterized by FTIR, XPS, HRTEM, and TG-DTA techniques. It is inferred from FTIR, TEM and XPS results that sebacic acid is coated on the surface of nano-ZnO. Data from TG-DTA indicate that the mass fraction of sebacic acid on the surface of nano-ZnO is about 14.5%. The wetting and dispersity experiments show that the surface property of nano-ZnO modified by sebacic acid is changed from hydrophilicity to hydrophobicity.
