【摘要】：印刷电子技术是指利用传统印刷技术制造电子器件与系统的科学与技术。基于该项技术工艺的大面积、柔性化与低成本的鲜明特征,在实际应用中可达到减少污染、降低材料浪费与成本的效果。氧化锌(ZnO)纳米材料作为一种常见且结构非常稳定的半导体金属氧化物,其高比表面积、表面活性强、对外界变化非常敏感等优势都非常适合用于制造压电传感器。此外,经疏水羧基修饰后的ZnO纳米材料具有优异的超疏水特性。本文将主要是ZnO纳米材料与印刷电子技术相结合,制备了柔性压电传感器和超疏水薄膜。本论文主要内容如下所述。采用高温氧化法制备了四针状纳米ZnO结构。通过X射线衍射、扫描电子显微镜等表征手段对其结构、形貌进行分析。结果表明,马弗炉的炉膛内温度对样品结构性能影响较大,炉膛内温为1050℃~1100℃时,样品为四针状ZnO结构,为反应的最佳温度。采用水热法成功制备了花状的ZnO纳米结构。实验结果表明,以醋酸锌为原材料,过氧化氢和PVP为络合物,在氢氧化钠碱性环境下的最佳反应条件为,真空干燥箱的温度为140℃,反应时长为2h,得到三维花状ZnO结构。四针状ZnO纳米颗粒相对于压力信号具有快速敏感的传感性能。通过四针状ZnO与carbon paste screen结合,以ZnO纳米四针颗粒制备敏感层、碳浆制备碳电极,制备得氧化锌压力传感器。本研究制得的以碳浆修饰电极和ZnO敏感层制备得压电传感器具有高灵敏度的压电传感性能。花状结构与四针状结构的纳米ZnO。在此基础上,通过低表面能物质硬脂酸的化学修饰,从而获得具有超疏水特性的表面,并通过添加聚氨酯等成功提高薄膜的附着力。
[Abstract]:Printing and electronic technology refers to the science and technology of making electronic devices and systems using traditional printing technology. Based on the characteristics of large area flexibility and low cost of this technology. In practical application, the effect of reducing pollution and material waste and cost can be achieved. Zinc oxide (ZnO) nanomaterials, as a common semiconductor metal oxide with very stable structure, have high specific surface area. High surface activity, very sensitive to external changes and other advantages are very suitable for the manufacture of piezoelectric sensors. The hydrophobic carboxyl modified ZnO nanomaterials have excellent superhydrophobic properties. In this paper, ZnO nanomaterials are mainly combined with printing and electronic technology. Flexible piezoelectric sensors and superhydrophobic films were prepared. The main contents of this thesis are as follows. Four needle-like nanocrystalline ZnO structures were prepared by high temperature oxidation method. The structure and morphology of the samples were analyzed by scanning electron microscope. The results showed that the temperature in the furnace of muffle furnace had a great influence on the structure and properties of the sample, and the temperature inside the furnace was 1050 鈩，
