【摘要】 用水热法以聚丙烯酰胺(PAM)为添加剂制备了氧化锌单晶纳米棒,并通过X-射线衍射(XRD)、透射电镜(TEM)及红外光谱(IR)和紫外-可见吸收光谱(UV-Vis)等测试手段对所得产物的组成和形貌进行了研究.TEM结果表明,所得产物为六角纤锌矿型氧化锌,纳米棒沿C轴取向生长,粒径分布均匀,长度2.5~3.0μm.当改变反应的溶剂,纳米棒的结构形态发生了很大改变.对PAM的作用和溶剂的影响作了简要论述.更多还原

【Abstract】 Single ZnO nanorods have been prepared by favorable hydrothermal method with polyacrylamide(PAM) as additives.The samples are characterized by X-ray diffraction(XRD),transmission electron microscopy(TEM),infrared absorption spectra(IR),and UV-Visible absorption spectra(UV-Vis).TEM results show that the nanorods have wurtzite(hexagonal) structure with good crystal state.The nanorods are straight and uniformly elongated along the c axis and show well-defined crystallographic faces.The length is about 2.5～3.0 μm.The possible function of PAM and the effects of solvent conditions are discussed.更多还原
