仿生层状材料的多功能化设计是拓展其应用领域的迫切需求。以珍珠层为结构模型，二维还原氧化石墨烯（RGO）和磁性石墨烯（MG）为无机构筑单元，聚乙烯醇（PVA）为胶，采用简单的蒸发诱导组装方法制备了人工杂化膜。该类珍珠质薄膜具有良好的力学性能，如高刚度、强度和韧性。仿生材料具有屏蔽电磁污染的性能。由于石墨烯的介电损耗和磁性纳米颗粒的磁损耗之间的协同作用，MG基类珍珠质薄膜比RGO薄膜具有更显着的电磁干扰（EMI）屏蔽性能。在8.2- 12.4GHz（X波段）范围内，膜厚仅为0.36mm的MG杂化膜的平均电磁屏蔽效能（SE）达20.3dB。这种轻质、柔韧、薄的MG人工杂化膜具有良好的EMI屏蔽应用潜力。
Multifunctional designs of biomimetic layered materials are in great demand for broadening their applications. Artificial hybrid films are fabricated using a simple evaporation-induced assembly method, using nacre as the structural model, two-dimensional reduced graphene oxide (RGO) and magnetic graphene (MG) as inorganic building blocks and poly(vinyl alcohol) (PVA) as glue. The nacre-like films exhibit good mechanical performance, such as high stiffness, strength and toughness. The biomimetic materials possess the shielding properties of electromagnetic pollution. MG based nacre-like films present more significant electromagnetic interference (EMI) shielding performance than RGO film, because of a synergism between dielectric loss of graphene and magnetic loss of magnetic nanoparticles. Average EMI shielding effectiveness (SE) reaches ∼20.3 dB over the frequency range of 8.2–12.4 GHz (X band) for MG hybrid film only 0.36 mm thick. The lightweight, flexible and thin MG artificial hybrid films possess good potential for EMI shielding applications.
