摘　　要：交联反应是高分子化学中的一类反应,常用于高聚物合成和改性,如塑料、树脂和橡胶。文中科普实验设计出一种极具创意、简单易行、绿色的改性海藻酸钠凝胶球的制备方法,并经红外光谱分析证实了交联反应的发生。在此基础上,对海藻酸钠凝胶球进行了创造性的设计,开发出改性海藻酸钠pH响应微球、漂流瓶等,在趣味性的体验中搭建了社会化的科普平台,向大众普及功能高分子材料及其交联反应的知识,形成科学认识事物的新思路。Crosslinking reaction is a kind of reaction in polymer chemistry,which is often used in the synthesis and modification of polymers,such as plastics,resins and rubber.In this popular science experiment,a creative,simple and green preparation method of modified sodium alginate gel ball was designed,and the crosslinking reaction was confirmed by infrared spectrum analysis.On this basis,the sodium alginate gel ball was creatively designed,and the modified sodium alginate pH response balls and drift bottles were developed.A socialized science popularization platform was built in the interesting experience,which strengthened the public's understanding of functional polymer materials and their crosslinking reactions,and formed a new idea of scientific understanding of things.
