| 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。 |

| Abstract: | 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. |
| Keywords: | nanosized ZnO stearic acid organic surface modification |
