Thermal Stability, Mechanical Properties and Solvent Resistance of PP/clay Nanocomposites Prepared by Melt Blending

Abstract:
In this research, the melt blending technique was used to prepare various polypropylene (PP) based nanocomposites. A commercial organoclay (denoted 15A) served as filler for PP matrix and the polypropylene grafted maleic anhydride (PP-g-MA) was used as compatibilizer. The morphology of the nanocomposites was studied using X-ray diffraction (XRD). XRD results showed that these nanocomposites are best described as intercalated systems. PP/Clay nanocomposites showed good thermal stability in the TGA analysis. By introducing about 3% clay in the nanocomposites, the onset temperature of the degradation increased by 22°C over that of the pure PP/PP-g-MA blend. Mechanical testing showed that the polypropylene nanocomposites had an enhanced Young,s modulus, hardness and slightly decreased tensile strength with increasing clay loading as compared the pure PP/PP-g-MA blend. The solvent resistance of PP/Clay nanocomposites is slightly decreased with increasing clay loading.
