摘要:: 磁性氣凝膠以其優異的性能受到越來越多的關注。目前，磁性氣凝膠的制備主要采用先將磁功能化材料分散到溶膠中，經凝膠、老化、干燥等工藝制得。磁功能化材料主要是指具有磁性的納米材料，其中應用最多的是鐵酸類，尤其以超順磁性四氧化三鐵的使用最為廣泛。而磁性氣凝膠的結構和性能因磁功能化納米材料、氣凝膠基體的不同而產生變化。無機磁性氣凝膠的基體主要是氧化硅、氧化鈦等氣凝膠，主要研究磁性顆粒與氣凝膠基體的相互作用機理，以及對材料的結構、性能的影響。而有機磁性氣凝膠基體主要是石墨烯、碳等柔性氣凝膠，主要應用在催化、吸附、生物分離等領域，具有磁性分離，使用效率、重復性能優異等特點。本文綜述了上述磁性氣凝膠的研究進展，介紹了磁性氣凝膠材料常用的制備方法、性能以及應用前景。

Abstract:: Magnetic aerogels have attracted much attention because of their special quality and functionality. The main method for the fabrication of magnetic aerogels is firstly dispersing magnetic nanoparticles into sol followed by gelling, aging and supercritical drying. The quality and structure of the magnetic aerogels produce changes with different aerogels matrix and magnetic nanoparticles which are used in many different fabrication methods. The magnetic nanoparticles mainly include MFe2O4, and the superparamagnetic iron oxide are the mostly used as magnetic functional materials. The interaction mechanisms between magnetic nanoparticles and aerogel matrix, texture and quality of the magnetic aerogels materials are always explored in inorganic magnetic aerogels synthesized with SiO2 aerogels and TiO2 aerogels as the matrix. However, the organic magnetic aerogels, graphene and carbon as the matrix, are focused on the application in catalysis, adsorption and bio-separation. This review aims to describe recent research progress of magnetic aerogels based on the synthesis, quality and their application in future of magnetic aerogels.
