Abstract
Montmorillonite clay has been treated with various concentrations of 3-aminopropyltriethoxysilane in various solvents such as water, tetrahydrofuran and toluene. Intercalation of aminosilanes between the clay layers have been confirmed from the increase in the average d-spacing obtained from X-ray diffraction (XRD). The two peaks observed in the x-ray diffraction results of clay modified with organosilanes in the water medium confirms the intercalation of amino silane as well as the tactoid formation due to the surface interaction of the surface -OH groups with water. Presence of organosilanes in modified clays has been further confirmed from the -CH asymmetric and symmetric stretching of >CH2 groups at 2920 and at 2855 cm-1. The amount of exchanged cations between organosilanes and clay has been determined using thermogravimetric analysis (TGA).The influence of modified nanoclay on the mechanical properties of the polyvinyl alcohol nanocomposite have been investigated. Significant improvement in mechanical properties like modulus and tensile strength has been observed.
