与大量已有文献记载的无机纳米结构相比，有机聚合得到的纳米结构的多样性是有限的。本文阐述了原位无机盐水解和气相聚合在金属氧化物-聚(3，4-乙二氧基噻吩基)(PEDOT)杂化纳米结构生长中的协同作用机理。稳定的聚合物生长和动力学控制的水解使高纵横比晶相的均匀沉积成为可能，例如β-FeOOH、TeO2和SnO2被导电聚合物覆盖。通过控制水解动力学，一步合成了形貌从一维纳米纤维到二维纳米花、纳米结构从整体到核壳的杂化材料。这种对水解和聚合之间联系的基本理解使纳米结构无机、聚合物和无机-有机杂化材料的未来发展成为可能。在这项研究的帮助下，储能电极成为可能。
The diversity of nanostructures obtained from organic polymerization is limited when compared to the huge amount of documented inorganic nanostructures. In this paper, we elucidate a synergistic mechanism between in situ inorganic salt hydrolysis and vapor-phase polymerization for the metal oxide-poly(3,4-ethylenedioxythiophene) (PEDOT) hybrid nanostructure growth. The steady state polymer growth and kinetically controlled hydrolysis enables homogeneous deposition of high-aspect-ratio crystal phases such as β-FeOOH, TeO2, and SnO2 coated by a conducting polymer. By controlling the hydrolysis kinetics, the hybrid material is synthesized in one step with morphologies controlled from 1D nanofibers to 2D nanoflowers and nanostructures from monolithic to core–shell. This fundamental understanding of the connection between hydrolysis and polymerization allows the future development of nanostructured inorganic, polymeric, and inorganic–organic hybrid materials. Enabled by this study, electrodes for energy storag...
