CNT/HDPE composites

Tang et al. (52) fabricated CNT-HDPE composite film by the following technique the first step was the preparation of a precursor material in the form of CNT-HDPE composite pellets. The pellets of neat HDPE and CNTs were combined in a beaker and heated in an oven at 200 °C for 10 min. Then the mixture was mechanically stirred to mix the CNTs into the melt and to form a viscous suspension. The dough-like suspension was then compressed and cooled to form a solid plate. The plate was then chopped into smaller pieces, which were fed into a twin-screw extruder. In the extruder, the temperature was maintained...

Xue et al. (16) observed that the wear rate of the UHMWPE/HDPE blend can be significantly reduced by adding CNTs, which can be correlated with an increase of the Young s modulus. The addition of 0.5 wt% CNTs to the UHMWPE/HDPE blend caused about 50% reduction of the wear rate, which is shown in Table 5.7. Besides, the composites reinforced with untreated CNTs had a better wear performance than the composites with pre-treated CNTs and the graphical...
