[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，
