The chemical method includes: chemical precipitation method, micro-emulsification method, sol-gel method, hydrothermal synthesis method, etc.; physical method includes: evaporation condensation method, mechanical ball milling method, etc.; chemical physical method includes: spray pyrolysis method, oxidation hot explosion Decomposition method, etc. In this study, an electric spark was used to generate a high-voltage discharge. The discharge voltage was about 1.5 kV to bombard the metal zinc substrate, and the nano zinc oxide was prepared to grow on a metal zinc substrate. The metal zinc substrate was placed in a dry atmosphere, water humidity 85%, salt concentration 5% seawater humidity 85%, high voltage discharge time was 1, 2, 3, 12 and 24 hours, respectively, to observe the nano zinc oxide Growing in the form of a metal zinc substrate. The experimental results obtained show that the nano zinc oxide has a sheet-like structure, and the size of the nano zinc oxide increases as the high voltage discharge time increases. The nano zinc oxide growth mechanism belongs to a solid phase converted into a gas phase, and is transformed from a gas phase to a solid phase deposition, that is, the metal zinc is rapidly bombarded by a high voltage discharge, and the solid phase metal zinc is instantaneously converted into a vapor phase metal zinc at a high temperature. Then, after high temperature oxidation, solid phase zinc oxide is deposited and grown on the metal zinc substrate. YANG,YAO-SHENG 楊耀昇 2019 學位論文 ; thesis 39 zh-TW
