Summary: This study explores the possibility of using graphene oxide as a modifying additive for polymer fiber-reinforced composites based on epoxy resin and basalt roving. The optimal content of graphene oxide has been determined experimentally to achieve the best physico-mechanical properties of the obtained polymer composite material. The study also investigates the efficiency of modifying the graphene oxide surface with APTES finishing additives and aminoacetic acid, which provides a chemical interaction at the polymer matrix-filler interface. The influence of graphene oxide and functionalizing additives on the polymer curing process was analyzed using the thermometric method and differential scanning calorimetry.

Summary: In this work, thermal analysis was conducted on olive/bamboo fiber-based epoxy hybrid composites. The study found that the incorporation of hybrid fibers improved the thermal stability compared to pure fiber composites. The storage modulus and loss modulus reduced, while the damping factor increased with hybrid fiber composites. Additionally, the OTL-B hybrid composite exhibited a lower coefficient of thermal expansion.

Summary: By dispersing reduced graphene oxide (RGO) and alumina into the epoxy matrix at different hybrid ratios, the synergy of RGO and alumina at 6:4 was found to enhance thermal conductivity by 23.4%, retain insulation properties, increase tensile strength, and improve storage modulus. The settling of alumina nanoparticles on the graphene surface inhibits electron transfer and eliminates graphene agglomerations, making it an important study for designing optimal multi-functional polymeric packaging materials.

Summary: ESBR latex was fabricated by emulsion polymerization and directly blended with epoxy resin to form EP/rubber composites, improving the toughness, crack resistance, and other mechanical properties of cured epoxy resins. The addition of 8 phr ESBR-11 increased the impact strength of the epoxy resin composite to 35.28 KJ/m(2), which was 127% higher than that of pure EP (15.18 KJ/m(2)). The dispersion and compatibility of ESBR latex significantly enhanced the mechanical properties of EP through uniform dispersion, good compatibility, and strong chemical bonding between components.

Summary: Highly thermal conductive polymer composites consisting of ND-OH and PVA were reported, with the interfacial properties influencing thermal conductivity. The interface strength between matrix and filler dominates thermal conductivity at low content, while filler-filler interaction dominates at high loadings. The PVA/ND-OH composite exhibited an ultrahigh thermal conductivity of 18.98 W m(-1) K-1 at 90 wt% ND-OH, showing potential for thermal management in next-generation electronic products.

Summary: In this study, polyether sulfone (PES) and silver nanoparticles functionalized boron nitride nanoplates (AgBNs) were used to enhance the thermal conductivity and mechanical properties of epoxy resin (EP) composites. The addition of silver nanoparticles helped increase the interfacial contact of boron nitride nanoplates, improving the heat conduction paths. The results showed that the inclusion of AgBNs significantly increased the thermal conductivity of the composites, and the introduction of PES improved the mechanical properties.

Summary: This study successfully obtained electrically conductive materials by adding functionalized multiwalled carbon nanotubes, and confirmed that carbon nanotubes as polymer reinforcements can increase tensile strength and strain percentage. However, increasing nanofiller percentages resulted in a drastic decrease in Young's modulus values.

Summary: The study found that introducing asphaltene fillers into epoxy resin affects the material properties, such as increasing viscosity, enhancing Young's modulus, and storage modulus. With an increase in asphaltene content, aggregation and network structures appear in the microstructure, while there is minimal impact on glass transition temperature, damping properties, and thermal stability.
