Based on the above experiments, the author studied the mixed metallic pillared and modified montmorillonites. The experimental result indicated that the microporous structure of Fe-Al-PLMs was affected by the changing of interlayer Fe-Al polymer with different Fe/Al ratio. But the presence of Al iron was helpful to incorporate Fe iron into interlayer of montmorillonites.. Introducing Zr helped Al-PLMs getting better larger spacing, thermal stability, surface area and pore volumes. Its successful to apply Zr-Al-PLMs to treat wastewater containing Cr iron. The experiment of modifying Al-PLMs by PVA showed that the order of adding starting materials (Al-pillaring solution, PVA, montmorillonite solution) was related to the property of Al-PLMs. The PVA as precursor was beneficial for Al to go into interlayer of the clay and to form larger basal spacing porous clay. The surface area and pore volumes of Al-PLMs increased mainly because of increasing the external surface area and mesoporous volumes after acid-activating. This conclusion confirmed that the microporous structure of pillaring clay depends upon the interlayer pillar.

实验结果表明：在Al-PLMs中引入Fe离子，不同Fe／Al比制得的Fe-Al-PLMs因层间的Fe-Al聚合离子结构不同而影响其微孔结构，但羟基Al离子的存在有利于Fe离子进入蒙脱石层间；在Al-PLMs中引入Zr离子，有助于其层间距、比表面积、孔体积增大，所得Zr-Al-PLMs应用于含Cr废水处理效果显著；PVA改性后的Al-PLMs其物化性质变化与铝柱化剂、PVA溶液、蒙脱石溶液三者不同添加顺序有关，说明PVA的前撑有利于Al进入蒙脱石层间得到较大层间距的Al-PLMs；经酸化处理得Al-acid-PLMs，其比表面积增大以外表面积为主，孔体积增大以中孔为主，这也证实了柱撑蒙脱石的微孔结构取决于其层间的柱化物。

Pristine Li-Al LDHs are synthesized by hydrothermal process in different reaction conditions by varying the aging time for 1 and 24 hours. Both the Li-Al layered double hydroxides (abbreviated as Li-Al LDH1 and Li-Al LDH24 for aging time 1 hour and 24 hours, respectively) were modified by using sulphanilic acid sodium salt hydrate, modified agent to form modified Li-Al LDH1-SAS and Li-Al LDH24-SAS. The morphology of the pristine layered double hydroxides are investigated by using wide angle X-rays diffraction, scanning electron microscopy and particle size analyzer which indicates that the crystallinity and aspect ratio is increased with increasing the aging time from 1 hour to 24 hours. The particle size of Li-Al LDH24 and Li-Al LDH1 are found to be ~1000 nm and ~250 nm, respectively. Both the pristine and modified LDHs are characterized by XRD, FTIR spectra and thermogravimetric analysis.

本研究目的在於改变长晶时间的长短，合成出同径大小的Li-Al LDHs，再经由改质剂sulphanilic acid sodium salt hydrate将Li-Al LDHs无机层材表面有机官能化制备出改质型Li-Al LDHs-SAS，於是进一步藉由扫描式电子显微镜、射径仪和穿透式电子显微镜等仪器分别观察LDHs改质前和改质后其主层结构型态上的变化；从中可以发现Li-Al LDHs随著长晶时间的增加其径有随之增大的趋势，但经有机化改质后其径会由於改质环境的影响明显低许多，针对此现象本实验将未改质和改质后之Li-Al人工无机层材制备成复材进一步探讨其在热性质和难燃特性上的为表现。
