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
