层状双金属氢氧化物(LDHs)是一类典型的二维无机层状纳米材料,由于其具有层间可插入性、良好的各向异性及热稳定性等特点,已被广泛应用于药物负载与释放、功能助剂、吸附、催化、能量储存、光学等领域.LDHs粉体材料在使用过程中存在容易流失、易聚集、不利于实现器件化等缺点.因此,近年来,关于LDHs基薄膜材料的研究引起了人们的广泛关注.其中,LDHs基柔性复合薄膜由于其便携性、可延展性和良好的力学性能等优点,在电化学存储、光电子器件、气体阻隔材料等领域表现出广阔的应用前景.本文围绕LDHs基柔性复合薄膜材料的研究工作,重点介绍了其制备方法和功能化研究进展,并展望了今后可能的发展方向.
Layered double metal hydroxides (LDHs) are typical two-dimensional inorganic layered nanomaterials that have been widely used in pharmaceuticals due to their inter-layer insertability, good anisotropy and thermal stability. Load and release, functional additives, adsorption, catalysis, energy storage, optics and other fields.LDHs powder materials are easy to be lost during use, easy to aggregate, which is not conducive to the realization of the device, etc. Therefore, in recent years, The research of thin film materials has aroused people’s attention, among them, LDHs-based flexible composite films have shown great advantages in electrochemical storage, optoelectronic devices and gas barrier materials due to their portability, ductility and good mechanical properties .Following the research work of LDHs-based flexible composite thin film materials, the research progress of its preparation methods and functionalization are introduced emphatically, and the possible future development direction is prospected.
