“…The efforts towards fullerene reinforced composites for practical applications that have been performed by using melt compounding are very limited in academic field. Fullerene has been used as additive in several thermoplastic polymers including polyethylene [13,14], polypropylene [15,16], polyamide [17] and poly(ethylene-co-acrylic acid) [18] with melt mixing method.…”

“…Some authors have deeply investigated the effect of CNTs on rheology of composites and the nucleating effect of small additions of CNTs [21, 22]. Many studies have focused on the thermal stabilization effect of CNTs on PP at high temperatures by thermo gravimetric analysis (TGA) characterization while others have focused on the stabilization effect at medium temperatures (oxidation), showing that a small addition of CNTs leads to a remarkable increase in characteristic degradation temperatures [9, 23–26]. In addition, CNTs have been used to improve mechanical performance of PP.…”

Carbon nanotubes (CNTs) have been added to polypropylene (PP) matrix to improve the overall performance of composites. The mixing process has been carried out by melt compounding using a twin screw co‐rotating extruder with different CNTs amounts in the 0.5–10 wt% from a concentrated PP‐CNTs masterbatch (20 wt% CNTs). Results show a remarkable increase in tensile strength and elastic modulus while a decrease in elongation at break is detected. With regard to thermal behavior, a remarkable increase in thermal stability at high temperatures (decomposition process studied by thermogravimetric analysis) is obtained as the CNTs amount increases. In addition to this improvement, a noticeable increase in thermal stability at medium temperatures (degradation onset determined by differential scanning calorimetry, DSC) is also observed. In a similar way, other property related to thermal and mechanical performance, such as Vicat softening temperature (VST) is improved with CNTs content. The optimum balance between cost and properties seems to be in the 1–3 wt% range. POLYM. ENG. SCI., 2011. © 2011 Society of Plastics Engineers

“…It has been found by Fang's group that C 60 could enhance thermal properties of PP, 35 HDPE, 36 and HDPE/EVA 37 by a free radical-trapping mechanism. Because polymer materials are usually used under air environment, from a practical application view, it is much more important to evaluate thermal stability of materials under air than under nitrogen.…”

Polyethylene (PE)/fullerene C 60 nanocomposites, and PE samples for comparison in the presence of 0.1 wt % and 0.3 wt % 2, 5-dimethyl-2, 5(tert-butylperoxy) hexane peroxide (DHBP) were prepared by melt mixing. FTIR characterization showed that reactive C 60 could be grafted onto PE chains via a radical mechanism. As a result, the dispersion state of C 60 was improved, and the chain extension reaction of PE macroradicals and final topological structures were largely influenced. Linear viscoelastic response of PE and PE/C 60 nanocomposites containing the same content of peroxide showed much difference. Furthermore, the results of dynamic time sweep tests demonstrated that the addition of C 60 could accelerate chain extension reaction. The presence of C 60 could largely improve the thermal stability of PE due to the radical scavenging nature of C 60 . However, the crystallization behavior, melting behavior and mechanical properties of both PE and PE/C 60 samples were mainly determined by the content of peroxide.
