The current status of knowledge regarding magnetic hybrid structures based on graphene or carbon nanotubes with various forms of iron oxides is reviewed. The paper starts with a summary of the preparation and properties of iron oxide nanoparticles, both untreated and coated with silica or polymer layers. In the next section, organic-inorganic hybrid materials obtained as a result of a combination of graphene or carbon nanotubes and iron chemical compounds are characterized and discussed. These hybrids constitute an increasing percentage of all consumable high performance biomedical, electronic, and energy materials due to their valuable properties and low production costs. The potential of their application as components of materials used in corrosion protection, catalysis, spintronics, biomedicine, photoelectrochemical water splitting and groundwater remediation, as well as magnetic nanoparticles in polymer matrices, are also presented. The last part of this review article is focused on reporting the most recent developments in design and the understanding of the properties of polymer composites reinforced with nanometer-sized iron oxide/graphene and iron oxide/carbon nanotubes hybrid fillers. The discussion presents comparative analysis of the magnetic, electromagnetic shielding, electrical, thermal, and mechanical properties of polymer composites with various iron oxide/graphene structures. It is shown that the introduction of hybrid filler nanoparticles into polymer matrices enhances both the macro- and microproperties of final composites as a result of synergistic effects of individual components and the simultaneous formation of an oriented filler network in the polymer. The reinforcing effect is related to the structure and geometry of hybrid nanoparticles applied as a filler, the interactions between the filler particles, their concentration in a composite, and the method of composite processing.
本文综述了基于石墨烯或碳纳米管与各种形式氧化铁的磁性杂化结构的研究现状。首先概述了未处理和包覆有二氧化硅或聚合物层的氧化铁纳米粒子的制备和性能。接下来，对通过石墨烯或碳纳米管与铁化合物结合得到的有机-无机杂化材料进行了表征和讨论。由于这些杂化材料具有优异的性能和较低的生产成本，它们在所有可消耗的高性能生物医学、电子和能源材料中的比例正在不断增加。还介绍了它们在腐蚀防护、催化、自旋电子学、生物医学、光电化学水分解和地下水修复以及聚合物基质中的磁性纳米粒子等领域作为材料组件的应用潜力。本文的最后一部分重点介绍了设计和理解纳米级氧化铁/石墨烯和氧化铁/碳纳米管杂化填料增强聚合物复合材料性能的最新进展。讨论比较了具有不同氧化铁/石墨烯结构的聚合物复合材料的磁、电磁屏蔽、电、热和机械性能。结果表明，由于各组分的协同效应以及在聚合物中同时形成取向填料网络，将杂化填料纳米粒子引入聚合物基体可同时提高复合材料的宏观和微观性能。增强效果与用作填料的杂化纳米粒子的结构和几何形状、填料颗粒之间的相互作用、它们在复合材料中的浓度以及复合材料的加工方法有关。
