摘要

Abstract

Synergistic effect in network formation of nylon-6 (PA6) nanocomposites containing one dimensional (1D) multi-walled carbon nanotubes (CNTs) and two dimensional (2D) layered double hydroxide (LDH) platelets on improving the mechanical properties has been studied. Mechanical tests show that

with incorporation of 1 wt% LDHs and 0.5 wt% CNTs

the tensile modulus

the yield strength as well as the hardness of the ternary composite are greatly improved by about 230%

128% and 110% respectively

as compared with neat PA6. This is mainly attributed to the unique

strong interactions between the CNTs and the LDHs as well as the jammed network-like structure thus formed between the nanofillers

as confirmed by the morphological observations. As compared with the binary nanocomposites

a much enhanced solid-like behavior in the terminal region of the rheological curves can clearly be observed for the ternary system

which also indicates the formation of a percolating filler network.
