“…The use of a MWCNT-based solvent-free nanofluid improved the dispersion of MWCNT in epoxy resin and adjusted the interface strength between MWCNT and the matrix. The investigation showed the effect of the polyetheramine on the properties of the epoxy [ 101 ]. Gold nanorods ionic nanocomposites were synthesized by step-wise surface modification having sulfonic acid as corona and ionically tethered to end-terminated with an amine group Jeffamine canopy [ 102 ].…”

“…MWCNT-filled epoxy composites were also promising materials for structural damping materials. In particular, the interfacial strength and MWCNT dispersion significantly influenced the mechanical and damping properties [ 101 ]. Indeed, excellent dispersion and weak interface strength could simultaneously enhance the damping properties and mechanical properties of the epoxy.…”

Ionic nanoparticle organic hybrids have been the focus of research for almost 20 years, however the substitution of ionic canopy by an ionic-entangled polymer matrix was implemented only recently, and can lead to the formulation of ionic nanocomposites. The functionalization of nanoparticle surface by covalently grafting a charged ligand (corona) interacting electrostatically with the oppositely charged canopy (polymer matrix) can promote the dispersion state and stability which are prerequisites for property “tuning”, polymer reinforcement, and fabrication of high-performance nanocomposites. Different types of nanoparticle, shape (spherical or anisotropic), loading, graft corona, polymer matrix type, charge density, molecular weight, can influence the nanoparticle dispersion state, and can alter the rheological, mechanical, electrical, self-healing, and shape-memory behavior of ionic nanocomposites. Such ionic nanocomposites can offer new properties and design possibilities in comparison to traditional polymer nanocomposites. However, to achieve a technological breakthrough by designing and developing such ionic nanomaterials, a synergy between experiments and simulation methods is necessary in order to obtain a fundamental understanding of the underlying physics and chemistry. Although there are a few coarse-grained simulation efforts to disclose the underlying physics, atomistic models and simulations that could shed light on the interphase, effect of polymer and nanoparticle chemistry on behavior, are completely absent.

“…Carbonaceous fillers, composed of sp 2 carbon-sp 2 carbon bonds, such as carbon black (CB), fullerenes, multi-(MWCNT) or single-(SWCNT) walled carbon nanotubes (CNT), carbon nanofibers, graphene nano-platelets (GNP) or graphene oxide (GO) are interesting reinforcements for nanocomposites. [65,66] High electrical (e.g., inplane graphite $4000, SWCNT $10 6 and MWCNT 10 5 S/cm 3 ) and thermal conductivities (e.g., in-plane graphite $298, SWCNT 6000 and MWCNT 2000 W/ [m K]), and excellent mechanical properties (e.g., single GNPs presents Young's modulus of 1 TPa and tensile strength of 100 GPa) [8,66] make these carbonaceous fillers interesting candidates for multifunctional composites.…”

Ionic liquid‐functionalized reinforcements in epoxy‐based composites: A systematic review

Several high‐performance reinforcements may be used in epoxy‐based composites. These commonly undergo chemical and/or physical treatments to enhance their interfacial interactions with polymer matrices. One recent technology comprises the use of ionic liquids (IL) as compatibilizers. This strategy may result in the development of composite materials with greater performance or multifunctional characteristics. Herein, an overview in the area of IL‐modified reinforcements and their effect on epoxy‐based composites is presented. The PRISMA protocol was followed for the review, and the focus of these studies was on the modification of carbon nanotubes, followed by graphene/graphite nanoplatelets and bio‐fillers. The most used IL were those based on imidazolium cation, especially 1‐butyl‐3‐methylimidazolium chloride. In most cases, when IL are used, the reinforcement displays stronger interactions with the epoxy matrix, depending the treatment route employed. Improved interfacial interactions are cited as the main reason for the improvement in the composite mechanical and thermal performances. It was also found that strategies for using low IL content, or routes that enable recovery of the salts after fiber/particle treatment, are still required, as well as the study of the influence of different amounts/types of IL on the structure of fillers and their relationships with the composite properties.

“…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.
