采用化学合成法制备了不同纳米尺寸的普鲁士蓝纳米粒子,均匀地分散在大片层的氧化石墨烯溶液中。通过抽滤制备大片层的普鲁士蓝-氧化石墨烯复合薄膜。将薄膜经HI处理,还原成石墨烯复合薄膜,制备了功能拓展、导电性增强、稳定的普鲁士蓝-石墨烯复合纳米膜材料。对膜材料进行表征研究了其晶体结构、分子光谱特征变化和宏观的二维结构和力学性能。复合薄膜可以被弯曲,呈现出较好的韧性。
Nanosized Prussian blue nanoparticles with different size were prepared by chemical synthesis method and dispersed in the large layer of graphene oxide solution. A large layer of Prussian Blue-Graphene oxide composite film was prepared by suction filtration. The films were treated with HI and reduced into graphene composite films to prepare Prussian blue-graphene composite nanofilms with extended functions, enhanced conductivity and stability. The membrane material was characterized by its crystal structure, molecular spectral characteristics and macroscopic two-dimensional structure and mechanical properties. Composite film can be bent, showing good toughness.
