摘要
本文以CO32-型镁铝水滑石为前体,乙二醇为分散介质,用返混沉淀法制备水杨酸根插层水滑石,并用XRD,FT-IR,UV-Vis等手段对样品进行了表征。结果表明,通过改变条件,水杨酸根离子可以引入镁铝水滑石层间,取代层间CO32-,从而得到一种具有屏蔽和吸收紫外能力的有机-无机复合功能材料。
Salicylate intercalated LDHs was prepared by anion - exchange method with Mg - Al - CO3^2- - LDHs being the precursor, and glycol as the dispersion medium. The results showed that a composite which has the ability shielding and absorbing ultraviolet was obtained through intrducing salicylate acid radical to LDHs substituting CO3^2-.
