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.

In this work, we report the microfluidic preparation of monodisperse imidazolium-based poly(ionic liquid) (PIL) microgels with a controlled size and morphology, and show that the imidazolium units in the microgel network can be exploited as reactive sites to efficiently access desired functional materials by a simple counteranion-exchange or conversion reaction.

Objective: A new poly(ionic liquid)(PIL), poly(p-vinylbenzyltriphenylphosphine hexafluorophosphate) (P[VBTPP][PF6]), was synthesized by quaternization, anion exchange reaction, and free radical polymerization. Then a series of the PIL were synthesized at different conditions. Methods: The specific heat capacity, glass-transition temperature and melting temperature of the synthesized PILs were measured by differential scanning calorimeter. The thermal conductivities of the PILs were measured by the laser flash analysis method. Results: Results showed that, under optimized synthesis conditions, P[VBTPP][PF6] as the thermal insulator had a high glass-transition temperature of 210.1°C, high melting point of 421.6°C, and a low thermal conductivity of 0.0920 W m-1 K-1 at 40.0°C (it was 0.105 W m-1 K-1 even at 180.0°C). The foamed sample exhibited much low thermal conductivity λ=0.0340 W m-1 K-1 at room temperature, which was comparable to a commercial polyurethane thermal insulating material although the latter had a much lower density. Conclusion: In addition, mixing the P[VBTPP][PF6] sample into polypropylene could obviously increase the Oxygen Index, revealing its efficient flame resistance. Therefore, P[VBTPP][PF6] is a potential thermal insulating material.
