“…Due to decreased viscosity, the dispersion state of the filler can be improved. However, worsened mechanical properties were reported in some cases when an organic solvent was used in polymers [45–49]. Loos et al used different concentrations of acetone (0, 7, 10, 13 wt %) to produce epoxy samples [50].…”

“…Some studies have revealed improvements in properties through nano-fillers [105–109]. Others have observed either no improvements [110–114], or indeed a worsening of properties [45–47 115–116]. The main reason for these differences was the functionalization of MLG and CNTs that affected the dispersion and the interactions of MLG and CNTs in/with the polymer [41].…”

SummaryOne of the main issues in the production of polymer nanocomposites is the dispersion state of filler as multilayered graphene (MLG) and carbon nanotubes (CNTs) tend to agglomerate due to van der Waals forces. The agglomeration can be avoided by using organic solvents, selecting suitable dispersion and production methods, and functionalizing the fillers. Another proposed method is the use of hybrid fillers as synergistic effects can cause an improvement in the dispersion state of the fillers. In this review article, various aspects of each process that can help avoid filler agglomeration and improve dispersion state are discussed in detail. This review article would be helpful for both current and prospective researchers in the field of MLG- and CNT-based polymer nanocomposites to achieve maximum enhancement in mechanical, thermal, and electrical properties of produced polymer nanocomposites.

“…They represent one the most promising materials for many applications such as catalytic support [33,34], polymer reinforcement agents [30], fuel cell electrodes [35], adsorbents [36], regenerative medicine [37] and hydrogen storage [38]. In addition, CNF have remarkable electronic, physical and mechanical properties [39,40,36,41,42], including high surface-to-volume area, high Young's modulus (138 GPa in the crystal region along the longitudinal direction), low coefficient of thermal expansion (10 À7 K À1 along the longitudinal direction) and an entangled-like structure [43].…”

Poly(ether ether ketone) /graphene/carbon fiber (PEEK/GE/CF) laminates with different weight percentage of GE were manufactured successfully through ball milling and hot-press processing. The effect of the GE on the morphology, thermal conductivity, friction performance, thermal and mechanical properties of composites was investigated. Scanning electron microscopy showed that the GE was uniformly distributed in matrix-rich regions.Thermal conductivity measurements demonstrated that addition of 0.7 wt% GE sharply improved the thermal conductivity of the laminates. Tribological tests revealed that the friction coefficient and wear rate rapidly decreased with the addition of GE. In the studied range, the friction reduction and wear resistance performance of PEEK/CF composites filled with 0.7 wt% GE is the most effective. Meanwhile, the obtained PEEK/GE/CF laminates also possessed excellent mechanical and thermal properties. Thus, graphene-reinforced PEEK/CF composites possessed better overall properties than conventional PEEK/CF composites.
