Organic modification of synthesized clay-magadiite
چکیده انگلیسی

A synthesized magadiite has been organically modified by n-hexadecyl trimethyl-ammonium bromide (CTAB), and then grafted by γ-aminopropyltriethoxysilane (APTS). The formation of the CTAB-magadiite was confirmed by XRD, which the basal spacing increases from 1.54 to 2.46 mn. The formation of the organic derivatives of magadiite was confirmed by XRD, FTIR, and 29Si CP-MAS NMR spectra. A silylating reagent of APTS was reacted to the CTAB exchanged magadiite. The copolymerization of the APTS modified magadiite presents a new layered silicate-organic compound. In this compound, a covalently bond formed between the interlayer spaces. It is dissimilar to the conventional clay-polymer systems in which the ionic interactions between silicates and organic modifiers are dominant.
