Influence of MWCNT morphology on dispersion and thermal properties of polyethylene nanocomposites

Influence of carbon nanotube–polymeric compatibilizer masterbatches on morphological, thermal, mechanical, and tribological properties of polyethylene

“…Incorporation of CNTs into PEgMA and HDPE-PEgMA increased the decomposition temperature (over 10 °C for 6 wt.% CNT addition to HDPEPEgMA) indicating that the presence of CNTs hinders the decomposition at high temperatures. Increase of the decomposition temperature of polyethylene by the addition of nanotubes has been reported earlier [18][19]41]. We observed only slight changes in crystallinity, melting temperature, and crystallization temperature when CNTs were added to PEgMA and HDPE-PEgMA.…”

Thermooxidative degradation of LDPE nanocomposites: Effect of surface treatments of fumed silica and boehmite alumina

“…This was usually reflected by a shift toward higher temperatures in the related thermogravimetric analysis (TGA) traces when comparing those of the plain and nanomodified polymer, respectively. This behavior was reported for low density and linear low density polyethylene (LDPE and LLDPE, respectively) modified with copper nanoparticles [2], layered double hydroxides [3][4], layered silicates (clays) [3,[5][6], silica [5], chalk [7], multiwall carbon nanotubes [8][9], alumina [10][11] and boehmite alumina [12][13]. Similar results were reported for fumed silica filled high density PE nanocomposites [14][15].…”

“…The latter govern the filler/matrix interactions. In fact, platy (disk-type) fillers, such as layered silicates [5] and fibrous (needlelike) ones, such as carbon nanotubes [8][9], markedly enhanced the resistance to thermooxidation, and even to fire. Comparing the thermal stability of LDPE/copper nano-and microcomposites it was found that the nanoparticles are more efficient "thermooxidative additives" than the microscaled ones [2].…”

Influence of shear-induced crystallization on the electrical conductivity of high density polyethylene carbon nanotube nanocomposites

“…However CNT chemical modification is complex and can be detrimental to mechanical or electrical properties. Therefore direct mixing of pristine CNT with PE is usually more attractive for applications [14][15][16][17]. The HDPE matrix conformation is strongly influenced at the interface with CNT as the latter are very effective nucleators of HDPE crystallization.…”
