“…Epoxy resins are extensively used in a wide range of applications [1], including adhesives [2,3], coatings [4,5], and high-performance composites [6,7], among others. However, as one of the main drawbacks is their inherent brittleness, much research has gone into finding ways to increase their toughness.…”

Ionic Liquid-Cured Epoxy/PCL Blends with Improved Toughness and Adhesive Properties

et al. 2022

In this work, ionic liquid (IL)-cured epoxy resins were modified by adding poly(ε-caprolactone) (PCL). Three different ILs were used in order to study how (a) the chemical structure of the ILs and (b) the PCL content affect the phase behaviour, microstructure, mechanical and adhesive properties. Regardless of the IL used or the PCL content, the obtained materials showed a single phase. The addition of PCL to the epoxy resin resulted in plasticizing of the network blends, lower glass transition temperatures (Tg), and crosslinking densities (νe). Low PCL contents did not have a significant impact on the mechanical properties. However, the adhesive properties improved significantly at low PCL contents. Higher PCL contents led to a significant increase in toughness, especially in the case of the imidazolium-based IL. The balance achieved between the mechanical and adhesive properties of these IL-cured epoxy/PCL blends constitutes an important step towards sustainability. This is because a biodegradable polymer (PCL) was used to substitute part of the epoxy resin, and the ILs—which are non-volatile and cure effectively at much lower contents—were used instead of conventional curing agents. Given the wide use of this kind of materials in the adhesive industry, the practical significance of these results must be emphasised.

“…The use of 2D materials, especially graphene, for epoxy resin reinforcement has been extensively documented. Important improvements in modulus, mechanical strength, toughness, and hardness have been reported, and the reader may consult interesting reviews [ 5 , 16 , 31 , 32 ]. In general, 2D nanomaterials have been studied in depth; however, the study of MXene-modified ERs is still in its beginning.…”

“…The literature on epoxy reinforced with nanofillers is extensive. Some recent reviews focus on using 2D nanofillers on polymers and epoxy resins [ 5 , 13 , 16 ], but they are either general or overly focused on one application. These publications scarcely mention several works with MXenes, partly owing to their novelty.…”

Epoxy resins are thermosets with interesting physicochemical properties for numerous engineering applications, and considerable efforts have been made to improve their performance by adding nanofillers to their formulations. MXenes are one of the most promising functional materials to use as nanofillers. They have attracted great interest due to their high electrical and thermal conductivity, hydrophilicity, high specific surface area and aspect ratio, and chemically active surface, compatible with a wide range of polymers. The use of MXenes as nanofillers in epoxy resins is incipient; nevertheless, the literature indicates a growing interest due to their good chemical compatibility and outstanding properties as composites, which widen the potential applications of epoxy resins. In this review, we report an overview of the recent progress in the development of MXene/epoxy nanocomposites and the contribution of nanofillers to the enhancement of properties. Particularly, their application for protective coatings (i.e., anticorrosive and friction and wear), electromagnetic-interference shielding, and composites is discussed. Finally, a discussion of the challenges in this topic is presented.

“…In electronics industry, epoxy is a known polymer, and it is broadly utilized in electrically conductive adhesives, integrated circuits, printed circuit boards and semiconductors [3,4]. In many high-performance applications, the use of epoxy resin is encountered with some challenges due to its brittle behavior, poor thermal and electrical properties [5]. Due to the rapid progress in electronics industry, and great efforts to produce smaller, faster, and more powerful electronic devices, the demands for multifunctional epoxy based resins have been extensively increased [6].…”

In this study, graphene aerogel (GA) was utilized to improve the multifunctionality of epoxy resin, which is highly necessary in its applications in integrated circuits and semiconductors. A scalable method with high capability for production of large size GA with desirable quality was proposed for GA synthesis. The synthesized GA was utilized to produce epoxy nanocomposite by epoxy resin infiltration in its macro-pores. Flexural modulus of the GA/epoxy nanocomposite was experimentally investigated and the results showed 30% increase with respect to the pure epoxy. The electrical conductivity of the nanocomposite reached to remarkable amount of 0.7 S/m, which is 13 orders of magnitudes more than the electrical conductivity of the neat epoxy. Moreover, the measured thermal conductivity for pure epoxy and GA/epoxy nanocomposites were 0.23 and 0.40 W/mK, respectively. The percentage of thermal conductivity enhancement per filler content is more than 101, which is in the top range of the reached values by various filler types in polymer nanocomposites. The proposed method could simultaneously increase the mechanical, electrical and thermal properties of epoxy polymer, and could be greatly beneficial for applications that need epoxy polymer with high multifunctionality.
