Long-chain polymer-assisted growth of one-dimensional (1D) nanostructures has been investigated in previous research. This kind mild method has lots of merits such as not requiring complex procedures, without template supporting etc. Can the short-chain polymer also be used to grow long nanowires? In the present work, a short-chain polymer (PEG400) was found to promote the formation of 1D ZnO nanostructures, which cannot be obtained by long-chain polymers (such as PEG10000). Moreover, nanowires and nanorods can be selectively synthesized by using short-chain polymers. The influence factors for the formation of 1D ZnO nanostructures were also investigated in detail. The XRD, Raman spectrum, XPS, SEM, TEM, ED, HRTEM, EDXA, and PL spectra have been provided for the characterization of the as-obtained nanowires and nanorods.
前人研究已对长链聚合物辅助下的一维（1D）纳米结构生长展开了探究。这种温和的方法具有诸多优点，比如无需复杂程序、无需模板支撑等。短链聚合物能否用于生长长纳米线呢？在本研究中，发现一种短链聚合物（PEG400）能促进一维ZnO纳米结构的形成，而长链聚合物（如PEG10000）无法得到此类结构。此外，利用短链聚合物可选择性地合成纳米线和纳米棒。同时还详细研究了影响一维ZnO纳米结构形成的因素。已提供XRD、拉曼光谱、XPS、SEM、TEM、ED、HRTEM、EDXA和PL光谱，用于对所制备的纳米线和纳米棒进行表征。
