Low Solubility

There were a large number of ionic liquids electrodeposition reported in the literature; but were still in the laboratory stage some problems in the practical application of electrodeposition remain such as easily reacted with moisture in the air (AlCl3ionic liquid), high cost, and corrosive (dialkylimidazolium cation andBF4−,PF6−ionic liquid). In addition to the above shortcomings, low solubility of many metal salts in ionic liquids limits the practical application. In order to solve the problem of low solubility, [Bmim]Cl could be added [Bmim]PF6, which could significantly increase the solubility of metal chlorides; this method could be commonly used in preparing metal electrochemical reduction of metal chlorides. Our study showed that adding cationic groups in hydroxyl ionic liquid could cause the good solubility of transition metal chlorides, such as CuCl2. Complexation of hydroxyl functional group and transition metal ions increased solubility, resulting in a larger deposition current density and surface electrochemical reduction of copper nanoparticles deposited on the metal Ni. The electroreduction mechanism and behavior of CuCl2in hydroxyl ionic liquid and the Cu nanoparticle formation mechanism were investigated based on a comparison between similar experiments in the ionic liquid.

Solvent Properties

Low solubility of terephthalic acid in common solvents makes its industrial production very difficult and not environmentally benign. Ionic liquids are known for their extraordinary solvent properties, with capability to dissolve a wide variety of materials, from common solvents to cellulose, opening new possibilities to find more suitable solvents for terephthalic acid. This work presents studies on the solubility of terephthalic acid in ionic liquids, and demonstrates that terephthalic acid is soluble in ionic liquids, such as 1-ethyl-3-methylimidazolium diethylphosphate, 1-butyl-3-methylimidazolium acetate, and dialkylimidazolium chlorides up to four times higher than in DMSO. Additionally, the temperature effect and correlation of ionic liquid structure with solubility efficiency are discussed.

Electromechanical Actuation

We report the development of conducting polymer electrochemical linear actuators from ionic liquids (as electrolytes) and polyaniline yarns and hollow fibres (as electrode materials). With a yarn-in-fibre configuration, these actuators were simple to fabricate and allowed two-electrode operation without a reference electrode. Typical electromechanical actuation behavior of expansion, with force decrease, and contraction, with force increase, during charge injection and removal has been realized for these actuators. Stress generation of these actuators was 0.42–0.85 MPa, which exceeds that of skeletal muscle (0.1–0.5 MPa). Practical application of these actuators has been successfully demonstrated by using the electrochemical actuation of a yarn-in-fibre actuator to drive a cantilever object. Importantly, this yarn-in-fibre configuration would allow the combination of an appropriate number of yarns as the actuation electrode to accomplish the mechanical task, depending on the weight of the object.
