Cure behavior of epoxy/MWCNT nanocomposites: The effect of nanotube surface modification

Effect of carbon nanofibers on the cure kinetics of unsaturated polyester resin: Thermal and chemorheological modelling

“…Many researchers have paid attention to this topic, demonstrating that no simple and univocal cure behaviour trend can be encountered when nanoparticles are mixed with a thermoset [8][9][10][11]. In particular, most of the studies were performed on epoxy systems, whereas according to our investigation, less attention has been focused on polyester-based nanocomposites.…”

Epoxy resin nanocomposites reinforced with ionized liquid stabilized carbon nanotubes

“…Figure 4 shows the DSC curves of the nanocomposites with 1 wt% f-CNT loading and pure epoxy. The glass transition temperatures of the polymer matrix depend on the free volume of the polymer, which is correlated to the affinity between the fillers and the polymer matrix [31,32]. Molecular motion in the bulk state depends on the presence of the vacancies or voids.…”

“…Only the main peak of the etherification reaction is observed and the reaction heat of the etherification reaction peak is approximately the total heat of the curing reaction. In addition, the functional groups on the chemically modified CNT surface act as the segments of the reaction agents to bridge the CNT and the epoxy resin [31]. However, the released heat is much smaller than that of the curing reaction, which indicates that it can be considered to be negligible.…”

“…In this study, the degree of curing of the f-CNT/epoxy nanocomposite was calculated. It is known that the epoxy group has three characteristic peaks in the fingerprint region: 830, 1250 and 913 cm −1 [31]. The band at 830 cm −1 is overlapped by the bending vibration of the two adjacent hydrogen atoms in the benzene ring.…”

Fabrication and properties of CNTs reinforced polymeric matrix nanocomposites for sports applications

“…The carbon nanotubes (CNTs) are used in advanced polymeric matrix composites to further improve the properties. CNT/epoxy nanocomposites were previously fabricated and studied for creep behavior [3], thermal and mechanical properties [4], morphology [5], cure behavior [6], effect of interfacial chemistry on molecular mobility [7], damping capacity in a broad temperature range [8], doping of nano-particles (titania) for synergistic effects in the multiphase nanocomposites [9], electrical and thermal conduction mechanisms [10], influence of cup-stacked CNTs [11], and effect of silane functionalization on the properties of CNT/epoxy nanocomposites [12].…”
