Highly porous, bendable laterally compressed graphene foam (cGF)/acrylonitrile butadiene styrene (ABS) composites are developed by dip coating of ABS on dense cellular-structured, freestanding cGFs. Electrical conductivities of the cGF/ABS composites are enhanced to 6.5 S/cm, higher than that of GF/ABS composites. An electromagnetic interference shielding effectiveness (SE) of 42.4 dB and a specific SE (SSE) of 300.7 dB·cm³/g are delivered, shielding 99.99% incident electromagnetic radiations. Compared with isotropic and fragile graphene foam (GF)/ABS composites, the cGF/ABS composites with 75% compression degree of GFs exhibit a distinctive two-layer structure which endows them with strong and bendable performances to a maximum wrapping angle of 50°. Synergistic effects of the unique two layer morphology, the balance between the thicknesses of two layers, the bending direction, and the compressively strong porous structure contributed to the highly bendable properties of 75%-cGF/ABS composites.

高度多孔，可弯曲的侧向压缩石墨烯泡沫（cGF）/丙烯腈丁二烯苯乙烯（ABS）复合材料是通过将ABS浸涂在致密的多孔结构，独立式cGF上而开发的。cGF / ABS复合材料的电导率提高到6.5 S / cm，高于GF / ABS复合材料的电导率。电磁干扰屏蔽效率（SE）为42.4 dB，特定SE（SSE）为300.7 dB·cm ³/ g，可屏蔽99.99％的入射电磁辐射。与各向同性和易碎的石墨烯泡沫（GF）/ ABS复合材料相比，压缩率为75％的cGF / ABS复合材料表现出独特的两层结构，这赋予了它们强大而可弯曲的性能，最大包裹角为50°。独特的两层形态，两层厚度之间的平衡，弯曲方向以及抗压性强的多孔结构的协同效应有助于实现75％-cGF / ABS复合材料的高度可弯曲性能。
