“…A series of work have been carried out to understand the confinement effect since then. Ionic liquids trapped in the nanoporous matrices of encapsulation shell belongs to three-dimensional restricted area, which covers the host matrix of metalorganic frameworks [161][162][163] , covalent organic frameworks [164][165][166] , nanoporous silicas (SiO2) [167,168] and carbons [169,170] , carbon nanotubes [171][172][173] , zeolites [174][175][176] , etc. Among these porous materials, nanoporous silicas (average pore sizes of 2.0 ~ 34.3 nm) is the most popular one due to their interconnected nanoporous structure, large surface area, high thermal/mechanical stability, nontoxicity and easy synthesis.…”

“…[25] To enhance these properties, highly conductive graphene, graphite, carbon nanotubes, and other carbonaceous materials have been used to fabricate composite PCMs. [44,47,48] Nevertheless, such an approach increases the total cost due to the cost of these carbon materials. In this context, biomass-derived carbon from agricultural waste could be an economically viable and more sustainable alternative.…”

Ionic liquids and their various analogues are without doubt the scientific sensation of the last few decades, paving the yellow brick road to a worldly version of Oz's green “Emerald city” – a more sustainable society. Their versatile suite of properties, originating from an almost inconceivably large number of possible cation and anion combinations, allows tuning of the structure to serve a desired purpose. Ionic liquids hence offer a myriad of useful applications from solvents to catalysts, through to lubricants, gas absorbers and azeotrope breakers. The purpose of this review is to explore the more unexpected of these applications, particularly in the energy space. It guides the reader through the application of ionic liquids and their analogues as i) phase change materials (PCMs) for thermal energy storage, ii) organic ionic plastic crystals (OIPCs), which have been studied as battery electrolytes and in gas separation, iii) key components in the nitrogen reduction reaction (NRR) for sustainable ammonia generation, iv) as electrolytes in aluminum ion batteries, and v) in other emerging technologies. We conclude that there is tremendous scope for further optimizing and tuning of the ionic liquid in its task, subject to sustainability imperatives in line with current global priorities, assisted by artificial intelligence.This article is protected by copyright.

To improve the thermal conductivity and mechanical properties of graphene‐acrylonitrile butadiene‐styrene plastic (ABS) composite, sub‐phosphite‐based ionic liquid (IL) was synthesized, and its structure was characterized by FTIR, NMR, and mass spectrometry. IL was as a modifier, and graphite powder (G powder) was modified by the ball milling method to obtain functional graphene thermal conductive filler (G‐IL). The structure and morphology of G‐IL were characterized by FTIR, X‐ray photoelectron spectroscopy (XPS), XRD, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The results of the Molau test showed that the presence of IL improved the interfacial interaction of G‐IL and ABS, enhanced the dispersion of G‐IL in the ABS matrix, made G‐IL contact with each other, and it was easier to establish a thermal conduction network and promote phonon transfer. The thermal conductivity of 9 wt% G‐IL/ABS composite was 0.392 W·m−1·k−1, which was 96% and 14% higher than that of pure ABS and G/ABS composite, respectively. The tensile strength and bending modulus of 9 wt% G‐IL/ABS composite were 44.89 and 2124.37 MPa, which were 13% and 11% higher than those of pure ABS, respectively. The impact strength of 9 wt% G‐IL/ABS composite was 34.17 kJ/m2. It was 18% and 7% higher than that of pure ABS and 9 wt% G‐IL/ABS, respectively.Highlights Phosphorus imidazole ionic liquids were prepared. Graphene was modified by ionic liquids through non‐covalent. Enhanced mechanical properties and thermal conductivity of G‐IL/ABS composites.
