Ionogel Fiber Mats: Functional Materials via Electrospinning of PMMA and the Ionic Liquid Bis(1-butyl-3-methyl-imidazolium) Tetrachloridocuprate(II), [Bmim]2[CuCl4]

“…However, a broad and weak band at 1569 cm −1 , a shoulder at 1167 cm −1 , and two very weak signals at 1336 and 1022 cm −1 in the spectra of the ionogels indicate that the IL is incorporated into the ionogel. The low intensity of the IL signals is due to the fact that the ionogel fibers contain only 10 % of IL (see Experimental Section for details); these low intensities correlate with earlier studies on ionogels with low IL fractions [41]. A further interesting observation is the absence of a water signal in the spectra of the ionogels in spite of the fact that both the IL and the PMMA exhibit broad bands at ca.…”

“…The spectra of the electrospun ionogels are a superposition of the two spectra of the individual components, similar to earlier work on PMMA/[Bmim] [FeCl 4 ] ionogels [39,41]. The bands arising from the IL are weak or only present as shoulders in the ionogel spectra.…”

“…Ionogels are IL/inorganic or IL/polymer hybrid materials combining the properties of the matrix such as mechanical robustness and the properties of the IL [35,36]. Nowadays luminescent [37 -39], photochemically active [40], magnetic [41,42], proton- [43] and other ionconductive [44,45], along with mechanically robust ionogels with adjustable mechanical properties [46] are known. Most ionogels so far are bulk materials with low surface areas [35,36].…”

“…[33,34] The current report adds another potentially useful property, the LCST behavior and partial recovery from aqueous solution, to the catalog. Indeed, Lee et 4 ] using metal chloride salts.…”

A transparent, flexible, ion conductive, and luminescent PMMA ionogel based on a Pt/Eu bimetallic complex and the ionic liquid [Bmim][N(Tf)2]

“…The fact that there is virtually no shift in the IR bands as the IL is incorporated into the PMMA suggests that the interaction between the IL and PMMA is rather weak. 51 Although there are a few reports on polymer-based ionogels in the literature, there is still a fair bit of uncertainty as far as the IL/polymer matrix interaction is concerned. Lodge has shown that polymeric networks act like a sponge, where the holes are entirely filled with IL.…”
