The adhesion of ice severely compromises the aerodynamic performance of aircrafts operating under critically low-temperature conditions to their surfaces. In this study, highly thermally and electrically conductive graphene foam (GrF) polymer composite is fabricated. GrF–polydimethylsiloxane (PDMS) deicing composite exhibits superior deicing efficiency of 477% and electrical conductivities of 500 S m–1 with only 0.1 vol % graphene foam addition as compared to other nanocarbon-based deicing systems. The three-dimensional interconnected architecture of GrF allows the effective deicing of surfaces by employing low power densities (0.2 W cm–2). Electrothermal stability of the GrF–PDMS composite was proven after enduring 100 cycles of the dc loading–unloading current. Moreover, multifunctional GrF–PDMS deicing composite provides simultaneous mechanical reinforcement by the effective transfer and absorption of loads resulting in a 23% and 18% increase in elastic modulus and tensile strength, respectively, as compared to pure PDMS. The enhanced efficiency of the GrF–PDMS deicing composite is a novel alternative to current high-power consumption deicing systems.

具有优异除冰效率和强度的三维石墨烯泡沫-聚合物复合材料
冰的粘附严重损害了在临界低温条件下运行的飞机的空气动力学性能。在这项研究中,制造了高导热导电石墨烯泡沫(GrF)聚合物复合材料。与其他基于纳米碳的除冰系统相比,GrF-聚二甲基硅氧烷(PDMS)除冰复合材料的除冰效率高达477%,电导率仅为500 S m –1,仅添加0.1%体积的石墨烯泡沫。GrF的三维互连体系结构通过采用低功率密度(0.2 W cm –2)。经受了100次直流负载-卸载电流循环后,证明了GrF-PDMS复合材料的电热稳定性。此外,多功能的GrF–PDMS除冰复合材料可通过有效地转移和吸收载荷同时提供机械增强作用,与纯PDMS相比,其弹性模量和拉伸强度分别提高了23%和18%。GrF–PDMS除冰复合材料的效率提高,是目前高功耗除冰系统的一种新型替代方案。
