Chemical modification of montmorillonite clay has been carried out using a trifunctional
alkoxysilane (3-aminopropyl)triethoxysilane (γ-APS). Silane grafting was achieved in dry and
hydrolyzing conditions. Pristine and silane grafted clay took part in interfacial polycondensation
(IPC) process to synthesis a layer of polyamide-66 onto the clay lamellae and therefore, enhance
their affinity with polyamide-66 matrix. Evidence of presence of grafted silane molecules and
presence of polyamide-66 on clay particles were provided by Fourier transform infrared (FTIR),
thermogravimetric analysis (TGA) and X-ray diffraction (XRD). Affinity evaluation of such
modified clays with polyamide-66 matrix was inspected through melt compounding of them with
polyamide-66 in another work.
