中文摘要：
以甲氧基嫁接高岭石（K/M）为前驱体,于常温条件下制备出N-（β-氨乙基）-γ-氨丙基三甲氧基硅烷嫁接高岭石（K/AEAPTS）,并应用X射线衍射、Fourier变换红外光谱、固态硅核磁共振谱分析、热分析、透射电子显微镜、比表面积及孔结构分析等手段对复合物进行分析。结果表明：高岭石经AEAPTS嫁接后,层间距扩大至1.91 nm,比表面积和孔容分别由10.0 m2/g、0.048 cm3/g增至22.4 m2/g、0.081 cm3/g。AEAPTS与高岭石的嫁接方式存在双齿（T2）和三齿（T3）两种结构,分别占42.2%和57.8%。AEAPTS的嫁接破坏了高岭石层间的氢键,加剧了高岭石自身结构中硅氧四面体片层与铝氧八面体片层之间的错位,使得K/AEAPTS复合物的部分片层剥离、卷曲变形。
英文摘要：
N-（β-aminoethyl）-γ-aminopropyl trimethoxy silane-grafted kaolinite compound （K/AEAPTS） was prepared with methoxy-grafted kaolinite （K/M） as an intermediate at ambient temperature. The product was characterized by X-ray diffraction, Fourier transform infrared spectroscopy, 29Si cross-polarizationmagic-angle spinning nuclear magnetic resonance spectroscopy, thermal analysis, transmission electron microscopy and adsorption-desorption technique, respectively. The AEAPTS-grafted kaolinite samples show that its physical-chemical properties, i.e., new d（001） value of 1.91 nm, specific surface area of 22.4 m2/g and pore volume of 0.08 1 cm3/g, respectively. The solid-state 29Si CP-MAS NMR spectra of K/AEAPTS exhibit T2（bidentate） and T3（tridentate） signals corresponding to the linkage of AEAPTS moieties, accounted for 42.2% and 57.8%, respectively. The K/AEAPTS compound appears clear scroll and exfoliation because a part of the hydrogen bonds are broken by AEAPTS.
