STUDY ON SURFACE MODIFICATION OF NANO-ZnO BASED ON PARALLED FLOW PRECIPITATION METHOD

本研究在应用并流沉淀法成功制备纳米氧化锌的基础上,利用超声波和微波技术研究纳米氧化锌的表面改性。通过表面改性剂种类的选择及分散介质、改性时间和温度、超声时间和功率等的试验研究,确定了表面改性纳米氧化锌制备的工艺条件。用XRD、SEM和IR对产品纳米氧化锌的形貌、粒度进行表征。结果表明所制取的纳米氧化锌呈类球形,其表面成功包覆了有机物。

In this paper, we successfully prepare nano - ZnO based on paralled flow precipitation method. Study on surface modification of nano-ZnO based on technologies of microwave and ultrasonic. The preparation technological conditions of surface modification nano - ZnO are determined by testing research on some parameters, such as category of dispersant, dispersion medium, emulsifying time and temperature, ultrasonic time and power. The appearance and granularity of surface modification of nano-ZnO are characterized by XRD,IR and SEM. The results show that nano - ZnO is quasi-spherical shapes and the nano-particles surface-coated with dispersant.
