In this review article, we provide an introduction to ferrogels, i.e. polymeric gels with embedded magnetic particles. Due to the interplay between magnetic and elastic properties of these materials, they are promising candidates for engineering and biomedical applications such as actuation and controlled drug release. Particular emphasis will be put on the polymer architecture of magnetic gels since it controls the degrees of freedom of the magnetic particles in the gel, and it is important for the particle-polymer coupling determining the mechanisms available for the gel deformation in magnetic fields. We report on the different polymer architectures that have been realized so far, and provide an overview of synthesis strategies and experimental techniques for the characterization of these materials. We further focus on theoretical and simulational studies carried out on magnetic gels, and highlight their contributions towards understanding the influence of the gels' polymer architecture.
在这篇综述文章中，我们介绍了铁凝胶，即含有嵌入磁性颗粒的聚合物凝胶。由于这些材料的磁性和弹性之间的相互作用，它们有望用于工程和生物医学应用，如驱动和可控药物释放。将特别强调磁性凝胶的聚合物结构，因为它控制着凝胶中磁性颗粒的自由度，并且对于决定凝胶在磁场中变形机制的颗粒 - 聚合物耦合非常重要。我们报道了迄今为止已实现的不同聚合物结构，并概述了这些材料表征的合成策略和实验技术。我们还重点关注了对磁性凝胶进行的理论和模拟研究，并突出了它们对理解凝胶聚合物结构影响的贡献。
