摘　　要：利用硬脂酸对纳米ZnO进行有机表面修饰;采用红外光谱(IR)、热分析(TG-DTA)、透射电镜(TEM)、润湿性实验、分散性实验等手段对表面改性前后的纳米ZnO进行表征。红外光谱和TEM表明,在纳米ZnO表面包覆有硬脂酸的有机层;热分析显示,包覆量约为18.98%;润湿性实验及分散性实验表明,经硬脂酸改性的纳米ZnO的表面由亲水性变为亲油性。The surface organic modification of nanosized ZnO was studied. The prepared samples were characterized by FTIR, TG-DTA, HRTEM techniques as well as wettability test and dispersion test. According to the spectra of FTIR and TEM, results showed that stearic acid has been coated on the surface of nano-ZnO. Data from TG-DTA indicated that the mass fraction of stearic acid on the surface of nano-ZnO is about 18.98%. The wettability and dispersion tests showed that the surface property of nano-ZnO changed from hydrophilic to hydrophobic after the stearic acid modification.
