“…The reduction potential can vary significantly with the choice of ionic liquid, much like the voltammetry of Ag|Ag + in ionic liquids [23,24]. Consequently, in order to confidently match the responses observed with the electrochemical characteristics of solubilised Co 2+ , a series of preliminary experiments were needed.…”

“…[7] Metal oxides, conducting polymers, and their composites with transition metal oxides are mostly employed as electrode materials in the fabrication of pseudocapacitors due to their high specific capacitance and extended operating voltage. [15,[22][23][24][25][26][27][28] Gold-, platinum-, stainless steel-, carbon-based electrodes and indium-doped tin oxide (ITO)-coated glasses have been employed as substrates for the deposition of PANI electrochemically [29][30][31][32][33] for specified application. Such reactions are also responsible for charge storage properties in rechargeable batteries but do not produce triangular GCDC but having plateau on the GCDC.…”

Ion diffusion rate and contact surface area of conducting polymers increased by composite formation with nanometric-size materials make them promising materials in the fabrication of energy storage devices. In this work, electronically conducting polyaniline and manganese oxide (PANI/MnO 2 ) nanofibrous composites were electrochemically co-deposited on stainless steel from binder-free electrolyte solution. Structural characterization and morphological characterization of the materials were performed with Fourier-transformed infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). SEM images show fibrous micro/nano-architecture of the composites with cluster networking structure having 200-500 nm length and 100-200 nm diameter. Electrochemical and energy storage properties of the assynthesized materials were investigated with cyclic voltammetry (CV), galvanostatic charge discharge curves(GCDC), and potentiostatic electrochemical impedance spectroscopy (PEIS) without any binders. Electrochemical measurements as well as galvanostatic charge discharge curves at 1 mA constant current have shown maximum specific capacitance of 149 F/g for the composite prepared with 0.15 M MnSO 4 in the co-deposition bath. The composites retain 67% specific capacitance even after 400 cycles, indicating the stability of synthesized composite. PEIS confirms the pseudocapacitive nature of the synthesized composites.

“…4,5 Conclusions This is the first high throughput combinatorial approach to anilinium-based PIL design to the best of our knowledge. While the closely related n,n-dialkylanilines (-NR 2 ) may form PILs which are liquid at room temperature, they will not be suitable polymerisable candidates due to the absence of protons from the amine groups which are necessary for the polymerisation process to occur.…”

We report the synthesis of new protic ionic liquids (PILs) based on aniline derivatives and the use of high-throughput (HT) techniques to screen possible candidates. In this work, a simple HT method was applied to rapidly screen different aniline derivatives against different acids in order to identify possible combinations that produce PILs. This was followed by repeating the HT process with a Chemspeed robotic synthesis platform for more accurate results. One of the successful combinations were then chosen to be synthesised on a larger scale for further analysis. The new PILs are of interest to the fields of ionic liquids, energy storage and especially, conducting polymers as they serve as solvents, electrolytes and monomers at the same time for possible electropolymerisation (i.e. a self-contained polymer precursor).
