摘要
分别以PEG400和PVA124为表面活性剂辅助水热法合成了氧化锌(ZnO)纳米棒。X射线衍射分析显示:产物为结晶良好的六角结构ZnO晶体,PEG400为表面活性剂制得的ZnO比PVA124为表面活性剂时的结晶性好。用透射电镜和选区电子衍射研究了不同表面活性剂对ZnO纳米棒形貌和结晶性的影响,解释了PEG400和PVA124对ZnO形貌影响的机理,并对ZnO的生长机制进行了初步探讨。
By using PEG400 and PVA124 as a surfactant respectively, zinc oxide （ZnO） nanorods with different diameters were synthesized hydrothermally. X-ray diffraction results show that the products are hexangular ZnO and the crystallinity of ZnO assisted by PEG400 is higher than that of ZnO assisted by PVA124. Transmission electron microscope and selected area electron diffraction were used to investigate the microstructure and crystallinity of the ZnO nanorods. The mechanism of the influence of PEG400 and PVA124 on the ZnO morphologies and the growth mechanism of ZnO nanorods were also discussed.
