A new Janus-like pellicle with top-bottom structure, functionalized by conductive aeolotropism, magnetism and luminescence (defined as a CML Janus-like pellicle), is conceived and constructed electrospinning by combining microcosmic with macroscopic partitions. [PANI/PMMA]//[Eu(BA)phen/PMMA] and [FeO/PMMA]//[Tb(BA)phen/PMMA] Janus-like microribbons are selected as building units to construct a conductive aeolotropism-luminescence layer (CL layer) and magnetism-luminescence layer (ML layer), and the two layers are combined to form a CML Janus-like pellicle. Macroscopic partition is achieved by designing the Janus-like structure of the pellicle, while Janus-like microribbons are used for the microcosmic partition by separating rare earth luminescent compounds from dark-colored magnetic FeO NPs and conductive PANI. The CML Janus-like pellicle has stronger luminescence compared to the contrast samples. The magnetism of the CML Janus-like pellicle can be adjusted by changing the doping amount of FeO NPs. The CML Janus-like pellicle can achieve a strong and variable conductive aeolotropism changing the doping amount of PANI and the highest conductive aeolotropism ratio can reach 10 times when the PANI content is 70%. Microcosmic and macroscopic partitions are simultaneously integrated into the CML Janus-like pellicle, which results in almost no detrimental mutual influences between the two layers, and the overall performances of the CML Janus-like pellicle are greatly improved.
通过将微观分区与宏观分区相结合的静电纺丝方法，构思并构建了一种具有上下结构、由导电各向异性、磁性和发光功能化的新型类Janus薄膜（定义为CML类Janus薄膜）。选择[PANI/PMMA]//[Eu(BA)phen/PMMA]和[FeO/PMMA]//[Tb(BA)phen/PMMA]类Janus微带作为构建单元，构建导电各向异性-发光层（CL层）和磁性-发光层（ML层），两层结合形成CML类Janus薄膜。通过设计薄膜的类Janus结构实现宏观分区，而类Janus微带则通过将稀土发光化合物与深色磁性FeO纳米颗粒和导电PANI分离来实现微观分区。与对照样品相比，CML类Janus薄膜具有更强的发光性能。CML类Janus薄膜的磁性可以通过改变FeO纳米颗粒的掺杂量来调节。CML类Janus薄膜通过改变PANI的掺杂量可以实现强且可变的导电各向异性，当PANI含量为70%时，最高导电各向异性比可达10倍。微观和宏观分区同时集成到CML类Janus薄膜中，使得两层之间几乎没有有害的相互影响，CML类Janus薄膜的整体性能得到了极大提高。
