An electrochemical amperometric ethylene sensor with solid polymer electrolyte (SPE) and semi-planar three electrode topology involving a working, pseudoreference, and counter electrode is presented. The polymer electrolyte is based on the ionic liquid 1-butyl 3-methylimidazolium bis(trifluoromethylsulfonyl)imide [BMIM][NTf2] immobilized in a poly(vinylidene fluoride) matrix. An innovative aerosol-jet printing technique was used to deposit the gold working electrode (WE) on the solid polymer electrolyte layer to make a unique electrochemical active SPE/WE interface. The analyte, gaseous ethylene, was detected by oxidation at 800 mV vs. the platinum pseudoreference electrode. The sensor parameters such as sensitivity, response/recovery time, repeatability, hysteresis, and limits of detection and quantification were determined and their relation to the morphology and microstructure of the SPE/WE interface examined. The use of additive printing techniques for sensor preparation demonstrates the potential of polymer electrolytes with respect to the mass production of printed electrochemical gas sensors.

Poly Vinylidene Fluoride

Conducting polymer (CP) actuators undergo volumetric changes due to the movement of dopant ions into the film during the electrical oxidation process. In this work, PPy/SPE/PPy electroactive tri-layer actuator was prepared by the electrochemical polymerization of pyrrole and the actuation characteristics were studied. An all-solid actuator, consisting of two polypyrrole (PPy) films and a solid polymer electrolyte (SPE) based on poly(vinylidene fluoride) (PVDF), clearly showed a reversible displacement in an atmosphere when a voltage was applied.

Poly Ionic Liquid

Due to the interesting properties of polymerized ionic liquids (PILs), studies are carried out to evaluate its performance when in composite with other synthetic polymers. Research on blend films prepared through solution casting are typically done to investigate their properties, however, electrospun fibers are of particular interest especially on technologies requiring mechanically robust and high surface area functional materials. In this work, poly (vinylidene fluoride)/poly (ionic liquid) (PVdF/PIL) nanofibers were produced through electrospinning. The PIL, poly (1-hexyl-3-vinyl imidazolium bromide), was synthesized through sonochemical solventless reaction followed by free radical polymerization. The structures of the synthesized IL and PIL were confirmed using FT-IR, 1H-NMR and 13C-NMR spectroscopy. Pseudocapacitor prototypes consisting of electrodeposited ZnO-based electrodes and the electrospun PVdF/PIL nanofibers as the polymer electrolyte were then fabricated at varied PIL concentrations. Contact angle measurements using sessile drop method revealed the decreasing wettability of the fibers attributed to the inherent hydrophobic nature of both the PVdF and PIL. Scanning electron micrographs also showed that increasing fiber diameters were obtained as the PIL concentration increases. In addition, cyclic voltammetry results showed that the calculated areal capacitance also increases with increasing PIL concentration. The development of pseudocapacitor assemblies utilizing ZnO-based electrodes and electrospun polymer electrolyte-separator membranes presents a better promise for the next-generation energy storage devices.

Electrochemical Double Layer

The sole aim of the present article is to develop an ionic liquid (IL)-doped solid polymer electrolyte for an electrochemical double-layer capacitor (EDLC). A solution cast technique was adopted to develop a solid polymer electrolyte of poly (vinylidene fluoride-co-hexafluoropropylene) as host polymer and low-viscosity IL (1-ethyl-3-methylimidazolium thiocyanate) as dopant. Electrochemical impedance spectroscopy measurement showed a six orders of magnitude enhancement in conductivity ( σ) by IL doping. A linear sweep voltammetric investigation of the electrolyte films exhibited a good electrochemical stability window of 3.6 V. Polarized optical microscopy of the synthesized films revealed a reduction in crystallinity by IL doping. Infrared spectroscopy further affirms the composite nature of the film. The maximum conductivity value of 2.65 mS/cm is obtained for 80% of the ionic-doped system. Using maximum conductivity film and porous carbon-based electrodes, we have developed EDLCs that show a specific capacitance value of 2.36 F/g.
