Chemical Modification Of Hectorite By Interlayer-Polymerization Of (3-Aminopropyl)trimethoxysilane
Published 1993 · Chemistry
Interlayer-polymerization of (3-aminopropyl)trimethoxysilane (APMS) was carried out in the interlayer of lithium hectorite(LHT), and hectorites modified by “tuning guest” such as alkylammonium hectorite(CnNHT) and pyridinium hectorite (PyHT). XRD measurements revealed that the polymer-LHT complex showed no d001 diffraction peaks, while the polymer-CnNHT and -PyHT complexes had definite basal spacings depending on the guest or the amount of APMS. The polymer-clay complexes were characterized by means of 29Si CP/MAS NMR and FT-IR spectra.
