Summary: This study compares the impact of different carbon nanofillers on the properties of hybrid conductive polymer composites, showing that multi-layered graphene nanoplatelets greatly improve overall performance while carbon black has a limited effect on mechanical properties and can even worsen electrical and thermal properties. The developed materials exceed recommended values for fuel cell bipolar plates, indicating high potential for application.

Summary: Through the utilization of nanotechnology, incorporating various modified and unmodified nanofillers into epoxy resins has gained momentum in enhancing their toughness. The chemical functionalization of nanofillers has been shown to significantly impact their dispersion in the EP matrix and subsequently influence the fracture properties of the composites. This review highlights the research progress in the toughening of EPs using carbon nanotubes, graphene, and their hybrids over the past six years.

Summary: This study synthesized four different silicate nanofillers and incorporated them into epoxy resin to enhance its mechanical properties. Characterization of the nanofillers and analysis of the composite materials were carried out using various techniques. The results showed that the addition of 3% of the nanofillers increased the tensile strength of the epoxy by 31.5%, 29.0%, 27.5%, and 23.5%, respectively.

Summary: The dispersion of carbon nanotubes and carbon nanofibers is a crucial step in the production of polymer-based nanocomposites, and it is a challenge due to the tendency of nanofillers to agglomerate. While the three-roll mill is an effective method for dispersion, it is time-consuming and limits industrial applications. The study aimed to establish an efficient ultrasonic dispersion process and compare it with the three-roll mill method, using rheological tests and image analysis to characterize dispersion quality and improve the process.

Summary: In this study, the processability and volumetric electrical properties of aerospace-grade RTM6 nanocomposites loaded with different carbon nanoparticles were investigated. Nanocomposites containing graphene nanoplatelets (GNP), single-walled carbon nanotubes (SWCNT), and hybrid GNP/SWCNT with different ratios were manufactured and analyzed. The hybrid nanofillers showed synergistic properties, providing better processability and maintaining high electrical conductivity compared to epoxy/SWCNT nanocomposites. The use of hybrid nanofillers overcame the manufacturing issues associated with SWCNTs, making it a promising candidate for aerospace-grade nanocomposites with multifunctional properties.

Summary: This article reviews recent advances in ternary diglycidyl ether of bisphenol A epoxy nanocomposites with nanoparticles and other modifiers, focusing on their mechanical and thermal properties. Various single toughening agents, in solid or liquid states, have been incorporated to enhance the properties of epoxy resins. The use of two appropriate modifiers for hybrid composites can potentially have a synergistic effect on performance properties. The study mainly focuses on widely used nanoclays with modifiers in both liquid and solid states. Some studies have confirmed the synergistic effect in the performance properties of epoxy matrix, but ongoing research is still exploring other nanoparticles and modifiers to further enhance the mechanical and thermal properties of epoxy resins.
