THERMAL ANALYSIS OF PVC/ MMT/ SIO2 NANOCOMPOSITE WITH DIFFERENTIAL SCANNING CALORIMETRY

Abstract

Interfacial interaction between nanoparticles and polymer matrix is responsible to change in the physical, chemical, mechanical and thermal properties of the composites. Thermal analysis for the nanocomposites of Montmorillonite (MMT)/ SiO2 and PVC has been carried out in this paper with Differential Scanning Calorimetry (DSC) technique. During analysis with the DSC technique, the temperature of glass transition, which has been recorded at 67.42oC in pristine PVC, showed the improvement up to 69.38oC in MMT nanocomposites, has further been enhanced to 72.550C for hybrid MMT+ SiO2- PVC nanocomposites. But the improvement in % crystallinity has been observed after adding 4wt. % SiO2 in the PVC matrix as compared to the other two types of nanocomposite from 8.73 to 10.94 due to uniform dispersion of nanoparticles. However, MMT content in PVC matrix decreases the % crystallinity because of non-uniform dispersion of MMT increases due to agglomeration of nanoparticles.
