Ionic liquids can typically be synthesized via protonation, alkylation, metathesis, or neutralization reactions. The many types of ionic liquids have increased their attractiveness to researchers for employment in various areas, including in polymer composites. Recently, ionic liquids have been employed to modify nanofillers for the fabrication of polymer nanocomposites with improved physicochemical properties. In this succinct review, four types of imidazolium-based ionic liquids that are employed as modifiers—specifically alkylimidazolium halide, alkylimidazolium hexafluorophosphate, alkylimidazolium tetrafluoroborate, and alkylimidazolium bistriflimide—are reviewed. Additionally, three types of ionic liquid-modified nanofiller/polymer nanocomposites—namely ionic liquid-nanofiller/thermoplastic nanocomposites, ionic liquid-nanofiller/elastomer nanocomposites, and ionic liquid-nanofiller/thermoset nanocomposites—are described as well. The effect of imidazolium-based ionic liquids on the thermo-mechanico-chemical properties of the polymer nanocomposites is also succinctly reviewed. This review can serve as an initial guide for polymer composite researchers in modifying nanofillers by means of ionic liquids for improving the performance of polymer nanocomposites.

Biodegradable polymers are an exceptional class of polymers that can be decomposed by bacteria. They have received significant interest from researchers in several fields. Besides this, biodegradable polymers can also be incorporated with fillers to fabricate biodegradable polymer composites. Recently, a variety of ionic liquids have also been applied in the fabrication of the polymer composites. In this brief review, two types of fillers that are utilized for the fabrication of biodegradable polymer composites, specifically organic fillers and inorganic fillers, are described. Three types of synthetic biodegradable polymers that are commonly used in biodegradable polymer composites, namely polylactic acid (PLA), polybutylene succinate (PBS), and polycaprolactone (PCL), are reviewed as well. Additionally, the influence of two types of ionic liquid, namely alkylimidazolium- and alkylphosphonium-based ionic liquids, on the mechanical, thermal, and chemical properties of the polymer composites, is also briefly reviewed. This review may be beneficial in providing insights into polymer composite investigators by enhancing the properties of biodegradable polymer composites via the employment of ionic liquids.

Energy Storage Material

As a new environmentally friendly solvent, ionic liquids have been investigated widely. The lack of physico-chemical properties data of ionic liquids has become a bottleneck that restricts their applications. In this study, the investigation of the density for binary mixtures of CnpyNTf2 (n = 2, 4, 5) and methanol is measured using Westphal balance. This study would be very important for the application of binary mixtures of ionic liquid and methanol in developing new energy storage material.

Dissolution of absorbent cotton (DP above 4000) using ionic liquids as solvent and regeneration was investigated. The results show that 1-ally-3-methylimidazolium chloride (AMIMCl) was a good solvent to dissolve absorbent cotton and a solution of 3 wt% can be reached in 18 min at 120°C. Besides, as the dissolving temperature increased the time needed for the cotton linters to dissolve decreased. The physic-chemical properties of the regenerated cellulose films were also characterized by XRD, FTIR and TGA analysis.

In this work we examined the industrial scale extraction process of ultra-low sulfur diesel with the help of simulation software ASPEN Plus®. This work focuses on the [Cnmim] [BF4] (imidazolium-based) ionic liquid and employed it in the extractive desulfurization of the dibenzothiophene (DBT) from the model diesel fuel under a very mild process condition. UNIFAC (uniquasi functional activity) was chosen as the thermodynamic method to model the ionic liquid on ASPEN Plus® and different physical and chemical properties were then taken from the literature to be incorporated in the simulation model. Different parametric analysis was studied for the removal of thiophene-based compounds from the model diesel. The results acquired shows the significance of imidazolium-based ionic liquids (ILs) for the extraction of S-contents from the liquid fuels at an optimal process conditions of 40 ℃ and 2 bar pressure with the 2.8: 1 ratio of ionic liquid and model diesel which validates the experimental results obtained previously in the literature.

Friction Reducing

A new series of functionalized ionic liquids containing ester-group were synthesized through a typical two-step way. The physicochemical properties of the functionalized ionic liquids were studied and the tribological properties of them as lubricants for steel-steel contact were evaluated on an SRV friction and wear tester and compared with the perfluoroalkylpolyether (PFPE), a low-volatility and fluorine containing lubricant, and a conventional ionic liquid, 1-butyl-3-methy imidazolium tetrafluoroborate (LB104), which is nonfunctionalized. Results showed that all the ionic liquids studied in this paper have better lubricities than PFPE as lubricants for steel-steel friction pairs. Functionalized ionic liquids show worse friction reducing abilities at relatively lower loads, which could be ascribed to their higher viscosities, but they always exhibit better anti-wear abilities than LB104. The possible friction mechanisms were discussed.
