摘　　要：己二胺(HMDA)作为一种重要的化工中间体,在尼龙-66的生产中扮演着重要角色,同时在化纤、服装纺织、化肥、医药、电子以及高分子材料等诸多领域得到广泛应用.针对水资中HMDA污染的高效检测问题,本文通过改变功能单体及其与交联剂的比例,成功制备了一种对HMDA具有敏感响应的反蛋白石结构聚合物光子晶体传感器(IOPPCs).研究结果表明,当功能单体为丙烯酸(AA),且功能单体与交联剂的比例为5∶0.5时,IOPPCs表现出最佳的响应性能.当HMDA浓度从1 mM增加到10 mM时,IOPPCs反射峰的红移量也从3 nm增加至140 nm,同时结构色由绿色变为红色,实现了可视化半定量检测.同时,所制备的IOPPCs具有良好的抗干扰性和重复使用性.Hexamethylenediamine(HMDA),as an important chemical intermediate,plays a crucial role in the production of nylon-66 and finds widespread applications in various fields such as synthetic fibers,textile manufacturing,fertilizers,pharmaceuticals,electronics,and polymer materials.Addressing the efficient detection of HMDA pollution in water,this study successfully prepared a photonic crystal sensor sensitive to HMDA by altering the ratio of functional monomers to crosslinker.The sensor,referred to as inverse opal polymeric photonic crystals(IOPPCs),exhibited optimal responsive performance when the functional monomer was acrylic acid(AA)and the ratio of functional monomer to crosslinker was 5∶0.5.Research results indicate that as the HMDA concentration increased from 1 mM to 10 mM,the redshift of the reflection of IOPPCs increased from 3 nm to 140 nm,accompanied by a color change from green to red,enabling visual semi-quantitative detection.Additionally,the prepared IOPPCs demonstrated good anti-interference property and reusability.
