Composite materials are made from two or more constituent materials with distinct physical or chemical properties that, when combined, produce a material with characteristics which are at least to some degree different from its individual components. Nanocomposite materials are composed of different materials of which at least one has nanoscale dimensions. Common types of nanocomposites consist of a combination of two different elements, with a nanoparticle that is linked to, or surrounded by, another organic or inorganic material, for example in a core-shell or heterostructure configuration. A general family of nanoparticle composites concerns the coating of a nanoscale material by a polymer, SiO2 or carbon. Other materials, such as graphene or graphene oxide (GO), are used as supports forming composites when nanoscale materials are deposited onto them. In this Review we focus on magnetic nanocomposites, describing their synthetic methods, physical properties and applications. Several types of nanocomposites are presented, according to their composition, morphology or surface functionalization. Their applications are largely due to the synergistic effects that appear thanks to the co-existence of two different materials and to their interface, resulting in properties often better than those of their single-phase components. Applications discussed concern magnetically separable catalysts, water treatment, diagnostics-sensing and biomedicine.

磁性纳米粒子复合材料：协同效应和应用
复合材料由两种或多种具有不同物理或化学性质的组成材料制成，当组合时，产生的材料的特性至少在某种程度上不同于其单个组件。纳米复合材料由不同材料组成，其中至少一种材料具有纳米级尺寸。常见类型的纳米复合材料由两种不同元素的组合组成，其中纳米颗粒与另一种有机或无机材料连接或包围，例如呈核壳或异质结构配置。纳米粒子复合材料的一般家族涉及聚合物、SiO 2或碳对纳米级材料的涂层。其他材料，例如石墨烯或氧化石墨烯（GO），当纳米级材料沉积在其上时，可用作形成复合材料的载体。在这篇综述中，我们重点关注磁性纳米复合材料，描述其合成方法、物理性能和应用。根据其组成、形态或表面功能化，提出了几种类型的纳米复合材料。它们的应用很大程度上是由于两种不同材料的共存及其界面所产生的协同效应，导致其性能通常优于单相组件的性能。讨论的应用涉及磁分离催化剂、水处理、诊断传感和生物医学。
