The exploration of a new family of flexible and high-performance electromagnetic shielding materials is of great significance to the next generation of intelligent electronic products. In this paper, we report a simple magnetic-electrospinning (MES) method for the preparation of a magnetic flexible film, γ-FeO nanoparticle-embedded polymeric nanofibers. By introducing the extra magnetic field force on γ-FeO nanoparticles within composite fibers, the critical voltage for spinning has been reduced, along with decreased fiber diameters. The MES fibers showed increased strength for the magnetic field alignment of the micro magnets, and the attraction between them assisted the increase in fiber strength. The MES fibers show modifications of the magnetic properties and electrical conductivity, thus leading to better electromagnetic shielding performance.
探索新型柔性高性能电磁屏蔽材料对下一代智能电子产品具有重要意义。本文报道了一种制备磁性柔性薄膜（γ-FeO纳米颗粒嵌入聚合物纳米纤维）的简单磁电纺丝（MES）方法。通过在复合纤维内的γ-FeO纳米颗粒上引入额外的磁场力，纺丝的临界电压降低，同时纤维直径减小。MES纤维对微磁体的磁场排列显示出增强的强度，并且它们之间的吸引力有助于提高纤维强度。MES纤维表现出磁性能和电导率的改变，从而导致更好的电磁屏蔽性能。
