“…Compared with the pure NPEF‐170, it increased by 66.53% and 51.09%, respectively. This increase is also better than some previous studies on the enhancement of epoxy resins by MWCNTs 37–39 . Zhang et al 41 added two kinds of surface sizing MWCNTs (MWCNT‐Bege and MWCNT‐Buge) to the epoxy matrix.…”

“…Compared with the pure NPEF‐170, it increased by 84.12%, 50.89%, and 8.18%, respectively. The increase is better than that of amino‐functionalized MWCNTs (Kashyap et al), 37 thiol‐functionalized MWCNTs (Wang et al 38 and Chen et al), 39 and nanostructured hybrid of Mt‐MWCNTs (Zeng et al) 40 for the increase of tensile strength and modulus of epoxy resin matrix. In our previous study of bisphenol A epoxy nanocomposites loaded with treated‐CNTs, the tensile strength and modulus increased by 6.34% and 14.35%, respectively 31 .…”

Epoxy resin is one of the most important matrix materials in the field of high performance composites. Its mechanical strength, toughness, and thermal stability are very important to the properties of composites. In this paper, the improvement of epoxy resin properties by carbon nanotubes (CNTs) is mainly studied. First, aniline trimer (AT) and polyethylene glycol octyl phenyl ether (Triton X‐100) are combined to modify CNTs. Then the dispersed CNTs (treated‐CNTs) are used to prepare bisphenol F epoxy nanocomposites. The dispersion of CNTs and fracture surface of composites are analyzed by SEM and TEM. The combination of AT and Triton X‐100 with CNTs is analyzed by UV–vis and FTIR. The mechanical, thermodynamic, tribological properties, and crosslinking density changes of epoxy composites are evaluated. The results show that AT and Triton X‐100 are successfully bonded to the surface of CNTs. The dispersion effect of treated‐CNTs in the composites is better than that of the original CNTs, which have a better reinforcing and toughening effect on the composites. The introduction of treated‐CNT reduces the crosslinking density and glass transition temperature of the composites, but does not affect the thermal stability of the composites before 300°C.

“…The presence of voids, that are observed in Figure 7D, might be due to improper the mixture of epoxy and CNTs. The accumulation of MWCNTs occurs due to their high surface area, π-π bonding, and van der Waals forces of attraction [20]. Individual CNTs sticking out of FE-SEM micrographs indicate poor adhesion between polymer and CNTs.…”

This research focuses on using Multiwalled carbon nanotubes to successfully produce MWCNTs/Epoxy nanocomposite with various MWNT weight loadings (0.25,0.50,1and2 % wt.). The samples were manufactured by utilizing an ultrasonic machine and a solution mixing method (MIT). The characterization, mechanical characteristics, and morphology of the resulting MWCNTs/Epoxy nanocomposites were investigated using FTIR, hardness, impact testing, and FE-SEM. According to the findings, different MWCNT loadings enhanced the mechanical performance of epoxy nanocomposites.Compared to pure epoxy, the impact result of MWCNTs/epoxy nanocomposite was recorded to increase as 33 %, 46 %, 75 %, and 108 %, respectively. Furthermore, increasing the amount of MWCNT nanofillers in nanocomposites samples improved their hardness to be as 0.4% ,2.20% ,2.89%. Finally, the FTIR and FE-SEM were also tested to find the structure of MWCNTs and dispersion quality.

“…It is a meaningful work to prepare high performance epoxy-based composites with high mechanical and thermal properties and multi-functional features. [1][2][3][4] One possible method is to introduce nanofillers (such as inorganic nanoparticles, nanowires, and nanotubes) into the epoxy resin to achieve this purpose. [5][6][7][8] Owing to their unique thermal conductivity, mechanical and thermal properties, multiwalled carbon nanotubes (MWCNTs) have been considered an ideal reinforcement for the epoxy resin, which holds the promise of delivering composite materials with high mechanical properties and multifunction.…”

In this study, we report an efficient and rapid technique to achieve the covalent functionalization of multiwalled carbon nanotubes (MWCNTs) by hyperbranched poly(thiol ether‐ester) (HPTEE) via thiol‐yne click chemistry method. The structures of the MWCNTs grafted with HPTEE (MWCNTs‐HPTEE) were characterized and their effects on the epoxy‐based composites were investigated. It was found that the hyperbranched polymers have been successfully grafted onto the MWCNTs surface thorough covalent bonds, which can greatly improve the dispersion of MWCNTs in epoxy matrix and the interfacial interaction between them, contributing to the largely enhanced mechanical and thermal properties. When 0.6 wt% MWCNTs‐HPTEE was added, the composites exhibited the best mechanical properties. An impressive 180% increase in the impact strength and 72.3% increase in flexural strength were observed with respect to the neat epoxy resin. Moreover, at the same filler content, the thermal stability and thermal conductivity of MWCNTs‐HPTEE/epoxy composites outperformed the composites containing the raw MWCNTs. Experimental results demonstrated that the resulted MWCNTs‐HPTEE are more effective on the improvement of properties of epoxy‐based composites as compared with raw MWCNTs.
