Abstract

Polymer nanocomposites exhibit superior mechanical properties, electrical properties, thermal and morphological properties. Polypropylene/PP-g-MAH/Mica silicate nanoclay Nanocomposites were prepared by melt compounding using Twin Screw Extruder. The tensile strength and modulus strength, Flexural strength and flexural modulus of PP/ PP-g-MAH/Nanoclay were highly increased with the loading of clay. The thermal properties were characterized by using differential scanning calorimeter (DSC) and thermo gravimetric analysis (TGA). PP-g-MAH provides better interfacial interactions between the two incompatible constituents, i.e. PP and nanoclay facilitates the exfoliation and dispersion of clay in PP matrix. FTIR analysis shows the effects of functional groups in the nanoclay with respect to potential interactions with the constituents. SEM Shows the microstructure of bulk specimen and phase arrangement of polymer nanocomposites of different constituent also studied.
