摘要
无机氧化物一维纳米材料在纳米器件、催化、能源等领域有广泛的应用前景。作为一种简单易行制备一维纳米材料的技术,静电纺丝法制备多元氧化物纳米纤维具有得天独厚的优势,但是纤维脆性增加了纳米纤维在柔性纳米器件制备的难度并限制了他的应用。本报告中,作者制备了多种多元氧化物纳米纤维,并且发展了一整套用于柔性器件制备的材料烧结、转移和器件组装技术。基于垂直纳米纤维阵列和水平排列纳米线阵列的柔性高性能纳米发电机被成功制备,能够实现紫外光传感、LED发光、LCD发光、生物电刺激等应用的供电。
One dimensional metal oxide nanomaterials are promising for the application in nano-device, catalyst and energy. Electrospinning, a simple technique, is superb for preparing multi-elements metal oxide nanofibers. However, the fragility of polycrystalline nanofibers increases the difficulty of device fabrication and hinders nanofibers' real application. Herein, we prepare several kinds of metal oxide nanofibers, whilst develop a set of methods for the nanofibers transfer and device assembly. Vertical and horizontal aligned nanofibers arrays are successfully used for fabricating high performance nanogenerator which can power UV sensor, LED, LCD and electric stock.
