Synthesis of Montmorillonite Clay/Poly(vinyl alcohol) Nanocomposites and Their Mechanical Properties

Anurag Kumar Gautam, Pragya Komal

Abstract

, that is indicator of higher crystallinity compare to pure PVA. Dynamic mechanical analysis (DMA) of MMT/PVA nanocomposite films showed an increase in the storage modulus. The optimum value of storage modulus obtained was 8,752 MPa on dispersing 1.0 wt% MMT clay in the PVA yielding 20.0% increase in the storage modulus compare to the pure PVA films. Thermo-gravimetric, analysis (TGA) of the MMT/PVA nanocomposite films also showed the increase in the thermal stability with respect to pure PVA films. The 1.0 wt% MMT clay loading in PVA, improved the thermal stability of MMT/PVA to 325 °C compared to 250 °C for pure PVA.
