摘要
设计一个操作简单的光热材料制备及在新型太阳能海水淡化中应用的创新性化学综合实验。通过一步浸泡涂覆的方法,制备出具有优异光热性能的材料,将其应用到新型技术——太阳能界面海水淡化中,可实现淡化水的收集和海水的浓缩。并通过实验表征材料微观形貌结构,探究太阳能利用效率,分析不同水样品的电导率。结合基础理论知识,引入前沿科学研究课题,实验方案设计既简单又具探究性,有利于培养学生的创新意识、创新思维和创新能力。
A simple-to-operate,innovative chemical synthesis experiment for the preparation of photothermal materials and their application in a novel solar-driven desalination was designed.By means of a one-step,dip-coating method,the materials with excellent photothermal properties can be fabricated using low-cost activated carbon and hydrophilic filter paper.These photothermal materials were applied to the emerging solar-driven interfacial desalination technology to achieve both clean water and concentrated seawater.The microscopic morphological structure of the materials was also experimentally characterized,the solar energy utilization efficiency was explored,as well as the electrical conductivity and Na+elemental content of various water samples were analyzed.Based on the basic theoretical knowledge learned,the cutting-edge scientific research topics was introduced.The design of experimental schemes was simple and exploratory,which was conducive to cultivating students innovative consciousness,creative thinking and innovative ability.
