摘　　要：以通过水热法在石英玻璃片表面合成的ZnO纳米棒为模板,在其表面生成聚多巴胺薄膜,然后与KMnO4反应,制备了MnO_2阵列纳米管。经表征发现,制备的MnO_2纳米管形态良好,在基底表面的附着力强;所制备的MnO_2为非晶型。由于ZnO模板易合成、易去除、形态好,且聚多巴胺薄膜的生成方法也很简便易行,使得该制备MnO_2纳米管阵列的方法具有简便、快捷、适用性广等的特性,对MnO_2新形态纳米结构的构建具有一定的启示作用。In this work,manganese dioxide（MnO_2） nanotube arrays are fabricated by using polydopamine coated-zinc oxide nanorod supported on quartz plates as template,followed by potassium permanganate reduction by polydopamine and the Zn O template removal. Characterization results showed that as-fabricated Mn O_2 nanotubes have well-defined tube morphology and strongly adhere to the substrate. The formed MnO_2 is amorphous. Polydopamine coated zinc oxide nanostructure as template exhibits several advantages,for example,it possesses diverse surface morphologies,and is easy to be synthesized and removed; the formation of polydopamine is also facile. These advantages might pave the way towards simple and facile fabrication of various MnO_2 nanostructures.
