Inverse gas chromatog. (IGC) was used as a tool to evaluate the surface parameters of three poly(1-alkyl-3-vinylimidazolium hexafluorophosphate) (P[CnVIM][PF6], n = 2, 4, 6) materials that were obtained by a free-radical polymerization IGC characterization was carried out at temperatures ranging between 303.15 and 343.15 K for determining the dispersive free energy (γds) as well as the Lewis acidity and basicity parameters of the three materials. The retention behavior of the probes on the surfaces of the three materials was analyzed by plotting the net retention volumes (Vn) of the probes as a function of temperature The dispersive free energy results revealed that all three materials have high γds values and that the γds value decreases in an almost linear fashion with increasing temperature The acid-base data for the three materials confirmed that the surfaces of all three materials can be considered to be amphoteric with a predominantly basic character and that the basicity decreases with increasing alkyl side chain length on the imidazolium backbone.

The semi-transparent solar cells are promising to be applied in building integrated photovoltaic (BIPV) and tandem solar cells. In this study, semi-transparent and stable solar cells are fabricated for BIPV by utilizing a poly (ethylene oxide) electrolyte and controlling the size of TiO2 nanoparticles and the thickness of the TiO2 film. The power conversion efficiency of the semi-transparent (> 50% transmittance at 620-750 nm) and quasi-solid solar cells is 5.78% under standard AM1.5G, 100 mW cm-2. The higher conductivity and smaller diffusion resistance of the quasi-solid electrolyte inside the mesoporous TiO2 film indicate the confinement effects of the polymer electrolyte inside a mesoporous TiO2 film. The unsealed semi-transparent and quasi-solid solar cell retains its initial efficiency during 1000 h irradiation in humid air.

Zwitterionic surfactants based on 3-(1-alkyl-3-imidazolio) propane-sulfonate ([ImS3-R] where R is octyl or dodecyl) is an emerging and important class of amphiphile due to their relevance as nano reactors for the synthesis of metallic nanoparticles and accelerated acid hydrolysis. The physicochem. properties of such synthesized imidazolium ring-containing zwitterionic surfactants have been characterized by surface tension and small-angle neutron scattering (SANS) techniques. Surface tension measurements were used to calculate several thermodn. parameters over a range of concentrations and temperatures (298-313 K). The results obtained showed a weak signature representing the critical micelle concentration (CMC) for ImS3-8, however, by increasing the alkyl length of the hydrophobic group to dodecyl, i.e., ImS3-8 to ImS3-12, the signature of the CMC was much more evident. As expected, the CMC for ImS3-12 shifted to a lower concentration An increase in temperature increased the surface activity and decreased the CMC of both zwitterionic surfactants, although the changes were small. Compared to classical surfactants, i.e., sodium dodecyl sulfate and dodecyl trimethylammonium bromide, the CMC of ImS3-12 is much lower. Modeling of SANS data demonstrated that the morphol. of the micelles formed by these amphiphiles may be described by the “classical” model, a central hydrophobic core, with a shell of hydrated headgroups. Due to their widespread applications in colloidal and interfacial science, the present study adds new insight to the fundamental understanding of these interesting imidazolium-based surface-active ionic liquids (ImS3-R).
