摘要(Abstract)：

针对磁性光子晶体基元纳米粒子多采用溶剂热法合成，受限于聚合物在特定还原性溶剂中的溶解性及其对高温、高压或碱性条件的稳定性，导致表面聚合物选择有限的问题，提出一种基于单宁酸(TA)与聚合物间氢键作用的通用后修饰方法，通过制备表面富含酚羟基的四氧化三铁Fe₃O₄@TA纳米粒子，利用TA与不同聚合物形成氢键，成功实现聚(4-苯乙烯磺酸共聚马来酸)钠盐、聚乙烯吡咯烷酮及乙烯基吡咯烷酮-乙酸乙烯酯共聚物对Fe₃O₄@TA纳米粒子的表面修饰，制备3类磁性光子晶体基元，表征它们的结构和性能。结果表明，3类聚合物功能化修饰的磁性光子晶体基元能够实现从粒径或磁性调控、光学性能增强到工艺优化及介质稳定性的系统性能优化，不同聚合物修饰的Fe₃O₄@TA纳米粒子具有光学增强作用，亲脂性共聚物修饰粒子还能够在高黏度树脂中稳定分散。
