| 摘 要： | 以层状镁铝双金属氢氧化物（MgAl Layered Double Hydroxides，Mg-Al LDHs）为主体，以有机紫外光稳定剂2-羟基-4-甲氧基二苯甲酮-5-磺酸（BP）为客体，结合焙烧复原法和阴离子交换法合成了具有超分子结构有机-无机插层复合物（MgAl-BP-LDHs），研究了层间阴离子、反应介质、pH值、反应时间等因素对于插层材料超分子结构的影响。用FTIR、XRD、TG-DTA、UV-Vis和粒度分析对其不同尺度的结构、热稳定性和紫外光稳定性等进行表征。结果表明，采用阴离子交换法难以进行插层反应；通过焙烧复原法可显著降低MgAl-LDHs层间CO2-离子，从而有利于BP阴离子交换进入MgAl-LDHs层间，在去离子水中，水温100℃，pH=7，反应时间为48 h，BP过饱和的条件下合成得到最高插层率的MgAl-BP-LDHs；主体水滑石层板与客体以静电力和氢键相互作用，得到的超分子结构材料具有良好的热稳定及兼具优异的紫外屏蔽、吸收性能，是一种新型的有机-无机复合光热稳定剂。

| Abstract: | The influence factors of 2-hydroxy-4-methoxy benzophenone-5-sulfonic acid (BP)-intercalated MgAl layered double hydroxides (MgAl-LDHs) reaction such as interlayer anions, solvent, pH values and reaction time, were investigated. The MgAl-BP-LDHs was prepared through anion-exchange under the optimal condition and characterized further by laser particle-size analysis, thermo-gravimetric analysis and ultraviolet-visible analysis, respectively. The XRD results indicate that the optimal reaction condition for the BP-intercalated MgAl-LDHs (MgAl-BP-LDHs) with high intercalation rate is 48 h in deionized water with pH value of 7. The results show that particle size distribution of the MgAl-BP-LDHs is narrower than that of MgAl-LDHs. The thermal stability of the MgAl-BP-LDHs is improved due to strong supramolecular interactions between MgAl-LDHs layers and BP anions. Compared with MgAl-LDHs and BP, the ultraviolet absorption range and ability of the MgAl-BP-LDHs are increased greatly due to the synergistic effect. |
