Abstract:

LDHs(Layered Double Hydroxides) are new type of layered materials with special structure and function.Due to their unique composition structural tunability and memory effect,LDHs have been widely studied and applied in many fields.The composition,structure and properties of LDHs materials and the application progress of LDHs functional materials in concrete,coatings,thermal insulation materials and other building materials in recent years were reviewed.The characteristics and application mechanism of LDHs materials were discussed.The problems of current LDHs materials,such as high preparation cost,harsh preparation process conditions,difficult stripping,immature positioning orientation and mechanism analysis of intercalation assembly,single use and so on were analyzed.Finally,the development and application of LDHs in supramolecular functional materials and stripping recombination were prospected.

Key words: layered double hydroxides(LDHs), functional materials, layered structure, construction materials
