通过ZnO纳米线和取向纳米棒阵列的生长，展示了一种合理制备智能和功能金属氧化物颗粒薄膜和涂层的新方法。该合成涉及无模板和无表面活性剂的水相方法，该方法能够在大规模，低成本和中等温度下生成复杂程度可控的高级金属氧化物薄膜。该策略包括通过化学和静电控制界面自由能来监测成核、生长和老化过程。它可以控制纳米、混沌和微晶的大小、表面形态、在各种衬底上的取向和晶体结构。
A novel approach to the rational fabrication of smart and functional metal oxide particulate thin films and coatings is demonstrated on the growth of ZnO nanowires and oriented nanorod arrays. The synthesis involves a template-less and surfactant-free aqueous method, which enables the generation of, at large-scale, low-cost, and moderate temperatures, advanced metal oxide thin films with controlled complexity. The strategy consists of monitoring of the nucleation, growth, and aging processes by means of chemical and electrostatic control of the interfacial free energy. It enables the control of the size of nano-, mess-, and microcrystallites, their surface morphology, orientations onto various substrates, and crystal structures.
