Abstract | This study investigated the sonication effect on the mechanical properties of thermoplastic natural rubber (TPNR) nanocomposites reinforced by multi-walled carbon nanotubes (MWCNTs). The TPNR nanocomposites were prepared using the melt blending method from polypropylene, natural rubber and liquid natural rubber as a compatibilizer, respectively, with 1% of MWCNTs. The results showed that a good dispersion on nanotubes was achieved by sonication. An optimal sonication time of 1 h was found to produce nanocomposites with maximum tensile and impact strength. The Young’s modulus, tensile strength, elongation at break and impact strength increased by almost 11%, 21%, 43% and 50%, respectively as compared with a pristine TPNR sample. The effect of sonication was also confirmed by dynamic mechanical analysis, it showed that the storage modulus E0, loss modulus E00 and glass transition temperature (Tg) also increased for all MWCNTs reinforced samples. Scanning electron micrographs confirm the effect of good dispersion of MWCNTs and their interfacial bonding in TPNR after sonication. |
