摘要
气凝胶是一种空间网状结构中充满气体分散介质的新型轻质纳米多孔材料,具有低密度、低导热率、高孔隙率和高比表面积等特殊性质,因而具有广阔的应用前景。磁性气凝胶即在外加磁场作用下能表现出显著磁性能的改性气凝胶材料,被广泛应用于防冲击、防噪隔热、储能器件和超强吸附材料等多个领域。在水处理中,磁性气凝胶除具备优异的吸附性能外,还容易被磁铁快速分离和回收,优势明显。此外,磁性气凝胶材料还在催化、医药、电化学等领域有着广泛的应用。本文综述了磁性气凝胶在吸附、催化、生物医学和电磁学领域的应用及其未来的发展趋势。
Aerogel is a new type of lightweight nano-porous solid material whose space grid structure is filled with gaseous dispersive medium,characterized by features such as low density,low heat conductivity,high porosity and high specific surface area. Accordingly,aerogel has broad application prospects. Magnetic aerogel is a modified aerogel material exhibiting remarkable magnetic properties under external magnetic field. It is widely used in many fields such as shock-resistant,heat-insulation,anti-noise,energy- storage devices and super adsorption material. In addition, with good adsorption performance,magnetic aerogel could be effectively separated and recycled by magnets in water treatment industry. Furthermore,magnetic aerogel materials are widely used in the field of catalysis,medicine, electrochemistry and so on. The applications and future trends of magnetic aerogels in adsorption,catalysis,biomedicine,electrical and magnetic science are reviewed in this paper.
