“…For comparison, the results obtained in a previous study for the neat resin samples containing different L/P resin ratios and 30 wt % ILE are shown. It has been previously observed that the composition of the epoxy resin blends had influence directly on the mechanical resistance of the samples, making them suitable for SPE applications. , For the neat resin samples, LP, and the mixtures modified with ionic liquid, LP(ILE), T g and E ′ at 30 °C followed a linear behavior depending on the content of L or P resin, from the higher values with the greater content of L to the lower values with the greater content of P ( T g of pristine L and P resins are 161 and 9 °C, respectively) . When the nanoparticles were included, this linearity was no longer observed, but it kept the tendency decreasing of T g and E ′ at 30 °C when the amount of P resin increased.…”

“…In these types of electrolytes, the ionic conductivity in S/cm was calculated using eq : where t is the thickness of the HEs in cm (between 0.20 and 0.25 cm), A is the area of the sample in cm 2 (6.0 cm 2 ), and R was obtained from the X -intercept of the high-frequency region in the Nyquist plot as previously reported . Two conductivity values were calculated using R 0 and R 1 (marked as σ 0 and σ 1 ) and correspond to the interface and bulk contributions, respectively …”

“…The additives included the obtained ionic conductivity and were ionic liquid and titania nanoparticles. Our optimized HE showed promising mechanical properties ( T g > 70 °C and storage modulus at 30 °C > 1 GPa), and it was used in a proof of concept for a supercapacitor made of graphene coated woven carbon fibers. , …”

“…Possibly, the most complex challenge of these devices is to design solid polymers electrolytes (SPEs) that allow high mechanical properties and high ionic conductivity. The main drawback of SPEs is that these two properties are often in conflict and electrolytes with high mechanical properties have low ionic conductivity and vice versa. ,, …”

The development of hybrid electrolytes (HEs) that allows high mechanical properties and high ionic conductivity is a key in the smart mobility progress. In this article, various solid polymer electrolytes (SPEs) based on a blend of epoxy resins, ionic liquid, and titania or alumina nanoparticles have been manufactured and their electrochemical and thermomechanical performances have been evaluated. The combination of SPE components providing the highest properties was studied, having a significant influence on the type of nanoparticles and their dispersion. The electrolyte with the best combination of properties was L65P35(ILE)Al2, which showed T g = 83 °C and E′ at 30 °C = 1.2 GPa as thermomechanical properties, and σ 0 = 7 × 10–4 S/cm, σ 1 = 1.6 × 10–6 S/cm, and C sp = 5.6 × 10–5 F/g at room temperature, as electrochemical properties. Moreover, the optimized electrolyte followed the Arrhenius ion transport model (E a = 24.7 kJ/mol). These results would be promising for use as hybrid electrolyte in structural applications.

“…Regarding other fillers modified with IL and used for the preparation of epoxy composites with multifunctional applications, Muñoz et al [ 115 ] used C 2 MImNTf 2 and titania nanoparticles to obtain a solid polymer electrolyte (SPE) based on DGEBA cured with DDS. The IL did not directly affect the electrochemical properties, but the greater filler dispersion improved storage modulus, in both glassy and rubbery states, thermal stability and T g .…”

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

et al. 2022

View full text Add to dashboard Cite

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.
