Simulation of the Conductive Process of Nano ZnO Varistors Based on Animation Plane Form

Abstract

Among many nano materials and chemical materials, zinc oxide nanomaterials have attracted researchers’ interest because of their high efficiency, low cost, easy preparation, and variable morphology. The purpose of this study is to explore the fabrication and conductive process of nano ZnO varistors under the simulation of an animation plane form. In this study, the chemical vapor deposition method was used to prepare nano ZnO. Then, ZnO nanomaterials were mixed with deionized water to form a suspension. Under the action of a micromechanical stirrer, impurities were removed by heat treatment, and then different amount of water was added to obtain a nano ZnO electrode. The conductive process and electrochemical properties of the nano ZnO electrode were investigated and analyzed. The results show that the pressure ratio of the varistor increases obviously after adding nano ZnO. In the range of 0–30%, the pressure ratio of the ZnO varistor increases with the increase in nano ZnO content. When w (nano ZnO) is 30%, the voltage ratio reaches 1.149 and the oxidation peak current ratio of LD decreases by 6%. Therefore, it is concluded that the electrode of nano ZnO varistor valve sheets maintains good stability for a LD conductivity detection process. It also plays an important role in electrochemical research.
