Thermal and mechanical properties of carbon nanotubes (CNT) reinforcedpoly(L-lactide) (PLLA)/thermoplastic Polyurethane (TPU) blends

In this study a series of carboxylated carbon nanotubes (CNTs) filled poly(L-lactide)(PLLA)/thermoplastic polyurethane (TPU) blends (۷۵/۲۵ wt%), prepared via melt mixing process,and the effect of inclusion of CNTs on the thermal and mechanical properties of nanocompositeblends was investigated. Furthermore, PLLA/CNTs master batch prepared before melt mixingprocess. Also, exothermic cold crystallization peaks and cold crystallization temperature of PLLAare reduced, and degree of melt crystallization increased by the addition of TPU and CNTs. Inaddition, a systematic enhancement found in Young’s modulus and tensile strength as a result ofCNTs inclusion.
