  采用离子液体1-乙基-3-甲基咪唑四氟硼酸盐([Emin]BF4)辅助合成具有核壳结构的Fe3O4@PPy复合材料。利用X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和傅里叶红外光谱(FT-IR)对Fe3O4@PPy的结构、微观形貌进行了表征分析,结果表明:利用离子液体辅助合成的样品在保持Fe3O4磁性的基础上,聚吡咯均匀包覆Fe3O4,形成核壳结构,且壳层厚度均一。

响应性光子晶体具有可调的周期性有序结构和可变的亮丽结构色[1-2],用它制成的光子晶体纸(PCP)在使用时不易产生视觉疲劳[3].但目前研制的PCP存在外场擦写速率慢,显示时间短、功能单一等问题.本文发展了在外磁场下的相转化法,制备了内填Fe3O4@聚丙烯酸(PAA)磁性光子链和聚乙二醇(PEG)的多孔结构醋酸纤维素(CA)多功能PCP.
