摘要
层状双金属氢氧化物(LDHs)是一类近年来发展迅速的阴离子型黏土,由于具有酸碱性、热稳定性、主体层板可调变性和层间客体阴离子可交换性等独特的特点,得到环保、医药、离子交换、材料阻燃等领域有关学者的高度关注,其中利用LDHs的插层技术研发或制备新型结构和功能材料的研究呈快速增长的态势,并已成为LDH研究的热点。从NO_(3)^(-)、SiO_(3)^(2-)、BO(3)^(3-)、H_(2)PO_(4)^(-)等无机阴离子插层技术,以及脂肪族羧酸根阴离子、芳香族羧酸根阴离子、有机磷酸酯阴离子、十二烷基磺酸根阴离子等有机阴离子插层技术两方面,系统阐述了LDHs的层间阴离子插层技术的国内外研究现状,并展望了LDHs的层间阴离子插层技术在塑料阻燃和生物质材料阻燃领域的应用前景。
Layered double hydroxide compounds(LDHs)are a kind of anionic clays,which have developed rapidly in recent years.Due to their unique characteristics such as acid-base,thermal stability,main laminate tunability and interlayer vip anion exchangeability,LDHs have been highly concerned by scholars in the fields of environmental protection,medicine,ion exchange,material flame retardance,etc.Among them,the research on the intercalation technology of LDHs and the preparation of new structural and functional materials have shown a rapid growth trend,and have become the focus of LDH research.From NO_(3)^(-),SiO_(3)^(2-),BO_(3)^(3-),H_(2)PO_(4)^(-) and other inorganic anion intercalation technologies,as well as aliphatic carboxylate anion,aromatic carboxylate anion,organic phosphate anion,dodecyl sulfonate anion and other organic anion intercalation technologies,the research status of interlayer anion intercalation technology of LDHs at home and abroad was systematically described.The future application of interlayer anion intercalation technology of LDHs in the field of plastic flame retardant and biomass material flame retardant was prospected.
