中文摘要：

通过共沉淀法、离子交换法、焙烧还原法制备出单十二烷基磷酸根离子（DDP）柱撑层状复合金属氢氧化物（LDHs）复合物。XRD和FT-IR分析表明,DDP进入到LDHs层间形成柱撑复合物,但采用3种工艺制备的复合物超分子结构有明显的不同：以共沉淀法制备的柱撑复合物层间距为3.15 nm,DDP在LDH层间呈倾斜双层排列,焙烧还原和离子交换法制备的复合物层间距为3.89 nm,DDP在LDH层间呈垂直双层排列。离子交换法制备出的DDP柱撑LDHs复合物中由于LDHs层间存在较强的静电作用力而不能使碳酸根被完全置换出来。

英文摘要：

Layered double hydroxides（LDHs）/ Lauryl alcohol phosphoric acid ester（DDP） pillared compounds were synthesized by three different methods of co-precipitation,ion-exchange and calcined-rehydration respectively.The supramolecular structures of pillared compounds were characterized by power X-ray diffraction and Fourier transformation infrared spectra.Results indicated that DDP could intercalated into the interlayer of LDHs by three methods,but the supramolecular structure of pillared compounds had significant difference：the interlayer space of compound obtained by co-precipitation method is 3.15 nm,which shown that DDP has declining double layers structure in the lnterlayer of LDH;for the ion-exchange and calcined-rehydration compounds,the interlayer spaces are 3.89 nm,which implied that DDP is upright double layers arrange in the lnterlayer of LDH.And for the ion-exchange pillared compound,there existed anion of carbonate in the interlayer,which was not completely replaced by the DDP due to the strong electrostatic force of interlayer of LDHs.
