The contact angle of liquid on the surface of solid materials is determined by the liquid surface tension, the solid surface tension, and the solid-liquid interface tension, which is an important parameter to measure the wettability of liquid on the surface of material. In this study, the metal mesh, a common material in daily life, is modified from hydrophilic and oleophylic to hydrophilic and oleophobic. The common preparation methods have certain limitations in popular science popularization, therefore, this paper innovatively optimized and improved the preparation scheme. The material prepared by a simple method shows good hydrophilic and oleophobic properties. Thus, this improved experiment has good scientific popularization. In addition, this popular science experiment also designed a variety of popular science exhibitions for different people, so as to improve the public's cognition of chemical knowledge and enhance their environmental awareness.
