“…Hence, the formed adhered coated films contributed to the metal and EP boundry. 32 , 33 In addition, any free hydroxyl groups on the surface of the Al 2 O 3 nanoparticles (used for pCNTs preparation) could form hydrogen bonds with the oxygen in EP, 35 which further validate the enhancement of mechanical properties in Figure 6 . As a result, it is proposed that the remaining metal catalyst might enhance the interfacial interaction between CNTs and epoxy resin.…”

Carbon nanotubes (CNTs) are promising nanofillers to enhance the mechanical performance of polymers. Through catalytic conversion, waste plastics can be converted into CNTs, which could be an alternative to commercial CNTs (cCNTs). Exploring a practical application of waste-plastic-derived CNTs will largely promote the technology development related to waste plastic management and CNT production. In this work, CNTs produced from plastics, named pCNTs, were applied as fillers to epoxy resin (EP), while commercial CNTs (cCNTs) were used as a reference. The carboxyl groups were effectively inserted on the CNT skeleton by a facile purification and modification. After ultrasonic dispersion, the modified pCNTs (M-pCNTs) were uniformly dispersed and loaded in the EP matrix. Better mechanical properties than EP were attained with a Young’s modulus of 3776.9 MPa, a tensile strength of 37.3 MPa, a fracture strain of 6.32%, and a fracture strength of 111.7 MPa with 2 wt % M-pCNT loading. Thus, pCNTs enhanced the toughness of the EP composites and simultaneously retained the stiffness. It was suggested that CNT pull-out and bridging were predominant toughening mechanisms for pCNT/EP composites. Notably, the coated film developed between residual metal in M-pCNTs and EP built a strong interfacial interaction and reinforced the EP composites.

“…By calculated, the optimal wear rate of ZrO 2 /Ti 3 C 2 /epoxy composite at 0.5% mass fraction is reduced by 79.3%, compared with neat epoxy. This can be ascribed that the uniform distribution of fillers in matrix and good interfacial bonding between fillers and epoxy matrix can improve tribological property of composites 43,44 . Similarly, the wear rates of Ti 3 C 2 /epoxy composites present the trend of raising first and then falling, with reach to the minimum value of 5.62 × 10 −14 m 3 /(N·m) at 0.5% mass fraction of Ti 3 C 2 microparticles.…”

Inherent brittleness and poor wear resistance of epoxy resin severely restricts its practical application in many applications. In this present, a micro-nano structured ZrO 2 /Ti 3 C 2 particle was employed to improve the tribological and thermo-mechanical properties of epoxy resin. The micro-nano structured ZrO 2 /Ti 3 C 2 particles are synthesized by hydrothermal growth of nano-ZrO 2 onto the surface of accordion-like Ti 3 C 2 , and the ZrO 2 /Ti 3 C 2 /epoxy composites are fabricated by solution blending and curing reaction. The surface morphology of ZrO 2 /Ti 3 C 2 particles and the fracture surface of ZrO 2 /Ti 3 C 2 /epoxy composites were investigated. Test results indicated that the wear rate, storage modulus and glass transition temperature of epoxy resin is effectively improved by incorporation of ZrO 2 /Ti 3 C 2 particles, maybe ascribing to the strong interfacial interaction between micro-nano structured ZrO 2 /Ti 3 C 2 and epoxy matrix. In addition, the wear mechanism of ZrO 2 /Ti 3 C 2 /epoxy composites were further revealed by analyzing their worn surfaces and wear debris.This work provides a promising strategy for improving the tribological and thermo-mechanical properties of epoxy.

“…On the other hand, the structural integrity of CNTs allows them to interlink with other filler materials [3]. Iron oxide (Fe3O4) nanoparticles, known for their magnetic responsiveness, significant mechanical strength, electrical conductivity, and thermal stability, present comprehensive properties when introduced through polymers [4][5][6]. Due to large surface area, crystalline nature, and surface characteristics, the introduction of Fe3O4 nanoparticles accompanied with CNTs as a hybrid filler in polymer matrices highly assists in achieving CNTs uniform dispersion, and interfacial bonding and thus synergistically improves the desired properties for different applications like electromagnetic interference shielding and data storage [7][8][9][10][11].…”

“…Tong et al [6] prepared CNTs/Fe3O4 hybrids by modified co-precipitation method and used a magnetic field to induce the alignment of these hybrids in carbon fabrics reinforced epoxy composites (CFRPCs). It was observed that shear strength and hardness were greatly improved due to the alignment of hybrids.…”

Integrating nanomaterials like carbon nanotubes (CNTs) and iron oxide (Fe3O4) into epoxy composites has significant interest due to their potential to enhance mechanical properties. This study evaluates the impact of dispersion quality on the mechanical performance of CNT/Fe3O4/Epoxy composites, comparing stirring and sonication methods at three different loadings: 0.1, 0.3, and 0.5 wt.%. Tensile testing revealed that sonicated composites consistently outperformed stirred composites, with a significant increase in elastic modulus and ultimate tensile strength (UTS). However, fracture strain decreased in both composite types compared to pure epoxy, with sonicated composites experiencing a more significant reduction than stirred composites. These results underscore the importance of high-quality dispersion for optimizing mechanical properties.
