Abstract

In this paper, the effect of CNT\\\'s surface modification on mechanical, thermal and morphological properties of nanocomposite with different content of CNTs were studied. CNT /high density polyethylene (HDPE) nanocomposites were prepared by mini twin-screw extruder. To modify the dispersion of MWCNTs in HDPE, the surface of CNTs was functionalized by HNO3 and stearic acid (SA).The tensile results show that addition of 5% of acid-treated CNT in HDPE cause to increase in Young\\\'s modulus and yield strength up to 4% and 6%, respectively compared to unmodified CNT/HDPE nanocomposite. The presence of the SA on CNTs can lead to slight decrease of the CNT-SA/HDPE strength properties, and there is a fracture toughness enhancement in CNT-SA/HDPE up to 10% compare to unmodified CNT/HDPE nanocomposite. Furthermore, the calculation of the stress whitening zone of all samples verify the fracture toughness data of CNT/HDPE nanocomposites. SEM images showed that the best dispersion of CNTs in the HDPE matrix was seen in CNT-SA/HDPE nanocomposite.
