摘要: 用XRD和SEM等手段研究了微孔层状磷酸铝[Al2P3O10(OH)2][C6NH8]的剥离和嵌入过程,发现该材料在醇/水溶液中能很好地剥离,形成胶体溶液,并能在一定条件下再结晶形成C2~C12烷基胺嵌入的层状新材料.当嵌入达到饱和时,有机胺在层间呈双层排列,并与层板成42.6°倾斜角.磷酸铝剥离和嵌入的难易与其层板结构间相互作用的强弱直接相关.

关键词: 微孔层状磷酸铝, 剥离, C2~C12烷基胺嵌入

Abstract: Layered microporous aluminophosphate [Al2P3O10(OH)2][C6NH8](AlP) was delaminated to form a well dispersed colloid in water-ethanol solution. New C2_C12 alkylamine intercalated materials of the aluminophosphate were reassembled in the solutions with dielectric constants in the range of 50—70 and an amine amount of 10 mmol/g AlP. The saturated C2_C12 alkylamine intercalated materials of AlP were packed with alkylamine bilayers tilted at an angle of about 42.6° in the interlayer region. The delamination and intercalation processes were followed by XRD and SEM measurements. The influence of layer structure on the delamination and reassembly processes was discussed.

Key words: Layered microporous aluminophosphate, Delamination, C2_C12 alkylamine intercalation
