通过涂覆氧化石墨烯，我们开发了一种化学途径来批量生产具有高导电性的长而细的氧化锰（MnO 2）纳米线。这些混合纳米线的平均直径约为25 nm，平均长度约为800 nm。这些纳米线的高电导率（约 189.51±4.51 µS）归因于导电氧化石墨烯的均匀涂层以及非键合锰原子的存在。纳米线的生长机制在理论上得到了支持，即通过在氧化石墨烯边缘处的锰和氧原子之间形成共价键，引发从氧化石墨烯到包裹结构的形态转变。
Through coating with graphene oxides, we have developed a chemical route to the bulk production of long, thin manganese oxide (MnO 2) nanowires that have high electrical conductivity. The average diameter of these hybrid nanowires is about 25 nm, and their average length is about 800 nm. The high electrical conductivity of these nanowires (ca. 189.51±4.51 µS) is ascribed to the homogeneous coating with conductive graphene oxides as well as the presence of non-bonding manganese atoms. The growth mechanism of the nanowires is theoretically supported by the initiation of morphological conversion from graphene oxide to wrapped structures through the formation of covalent bonds between manganese and oxygen atoms at the graphene oxide edge.
