以Mg/Al-CO_3-LDH为前体,采用离子交换法制备了脂肪酸(丁二酸、己二酸、癸二酸、酒石酸)和芳香酸(笨甲酸、水杨酸)柱撑水滑石复合材料,并利用XRD、FT-IR、TG和DTA技术对样品进行了结构表征和性能测试.结果表明,通过控制离子交换条件,6种有机酸根离子可以插入水滑石的层间完全取代CO_3~(2-),形成具有超分子结构稳定的有机酸阴离子/LDHs复合材料.
Adipic acids and aromatic acid are intercalated into magnesium aluminum layered double hydroxides (Mg/Al-LDHs) by the ion-exchange method. The samples prepared are characterized by XRD, FT-IR, TG and DTA.The results show that the initial interlayer carbonate ions can be completely replaced by the organic acid anion under controlled conditions,and supermolecular structure is formed and the structure models are given out.
