摘要:

层状双金属氢氧化物(LDHs)是由带结构正电荷的片层和层间阴离子有序组装而成的层状无机化合物, 近期其剥离研究受到关注. 剥离后的LDHs纳米片可被看做“无机高分子”, 具有纳米尺度的开放结构, 既可作为理论研究模型, 又可作为新型基元组装功能复合纳米结构或材料, 具有显著的应用潜力. 本文对LDHs的剥离方法、剥离产物的表征方法及其应用研究现状进行了综述, 并对今后的研究方向进行了展望.

Abstract:

Layered double hydroxides (LDHs) are a class of layered inorganic materials that consist of structurally positively charged layers and exchangeable anions in the interlayer gallery for charge balance. The delamination of LDHs has attracted much attention in the last decade because it is an effective way for exposing the inner surfaces of the host layers. Delaminated nanosheets may be referred to as “macromolecules”, and they have opened nanostructures. They can be used as an ideal model system and as building blocks for various multilayer ultrathin films and functional nanocomposites. In this article, we outline the progress made regarding the delamination of LDHs and pose future challenges.

Key words: Layered double hydroxide, Hydrotalcite-like compound, Delamination, Formamide
