摘　　要：液体在固体表面的接触角大小由液体表面张力、固体表面张力和固-液界面张力共同决定,是衡量该液体对材料表面润湿性能的重要参数。本文以生活中常见的金属网为基底,将其制备成亲水疏油材料。常见的制备方法在科普推广中存在一定的局限性,因此本文创新性地进行制备方案的优化改进,制备得到的材料同样具有很好的亲水疏油特性,从而具有很好的科普性和可推广性。并且,本科普实验还针对不同人群,设计了丰富多彩的科普展示,从而提高大众对化学知识的认知,增强大家的环保意识。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.
