Valorization of Post-consumer PP by (Un)modified Tunisian Clay Nanoparticles Incorporation
- 16 Downloads
Modified (or unmodified) Tunisian clay nanoparticles were incorporated as nanofillers in post-consumer polypropylene (PCPP) polymer matrix in order to improve its inherent properties. PCPP loaded with Na-clay or organoclay nanocomposites were elaborated by melt intercalation method. Morphological, thermal and rheological properties of prepared nanocomposites were then evaluated. SEM observations showed better nanoparticles dispersion when PCPP was filled with organoclay compared to Na-clay. According to FTIR analysis, the increase of PCPP band intensity is much higher when using organoclay, suggesting that the nanocomposites might have more intercalation of organoclay aggregates than in the case of filled with Na-clay. Thermal gravimetric and thermal degradation analyses results confirmed that the addition of modified clay allows better thermal stability than PCPP filled with unmodified clay. This result was confirmed by DSC analysis. We deduced from the rheological analysis that PCPP storage modulus G′ and loss modulus G″ increased with the addition of clay nanoparticles. This increase was higher when the organo-modified clay was dispersed into the PCPP matrix, demonstrating the reinforcing effect of the latter on PCPP polymer.
