“…To detect the possible interactions between MimMP and silica, a peak fitting program on the XPS spectra of silica and silica–MimMP was performed 51. As shown in the upper curve in Figure 2, the binding energies of silicon in the silanol group (SiOH) and in the silicon–oxygen bond (SiOSi) were located at 105.0 and 103.7 eV, respectively 52.…”

To introduce thiol-ene chemistry in the modification of composites by ionic liquid (IL), a novel functional IL, 1-methylimidazolium mercaptopropionate (MimMP), was synthesized and investigated as a modifier for styrene-butadiene rubber/silica composites. MimMP could be hydrogen-bonded with silica and react with the double bonds of rubber chains via thiol-ene chemistry. The filler networking, curing behavior, filler dispersion, crosslink density, and mechanical performance were fully studied. The filler networking in the uncured rubber compounds was effectively restrained. The vulcanization was largely accelerated by MimMP. The interfacial interaction was quantitatively evaluated and found to consistently increase with increasing MimMP. The mechanical performance and abrasion resistance of the modified vulcanizates improved considerably. The remarkable improvements were mainly ascribed to the improved interfacial structure comprised of MimMP-silica hydrogen bonding and MimMP-rubber covalent bonds via thiol-ene chemistry.

“…However, due to the limited compatibility toward rubber [27][28][29] and the environmental unfriendliness of the fluorine containing anions [30], these two factors deter the common ILs such as 1-butly-3-methylimidazole hexafluorophosphate (BmimPF 6 ) from their corresponding promising applications in modifying rubber/filler composites. Previously, we have confirmed that, via special treating methods, such as solution dispersion, mechanical grinding or microwave irradiation treatment, BmimPF 6 could not only influence surface properties of rubber fillers, but also improve the mechanical performance of the filled polymer materials [31][32][33]. However, an excess loading of BmimPF 6 proved to be unacceptable because of its poor interaction toward rubber chains and its high economic cost.…”

Abstract.A novel functional ionic liquid (IL), 1-methylimidazolium methacrylate (MimMa), was synthesized for modifying styrene butadiene rubber (SBR)/silica composites. MimMa was found to be readily polymerized via the initiated radical mechanism and could be analogously grafted onto rubber chains during vulcanization. Substantial hydrogen bonding between polymerized MimMa (poly(MimMa)) and silica can facilitate the silica dispersion and improve the SBR/silica interfacial bonding. Filler networking, curing behavior, silica dispersion and mechanical performance of the modified SBR/silica composites were studied. With a low concentration of MimMa, remarkable improvements in the interfacial interactions and mechanical properties were achieved which was attributed to the improved silica dispersion and strengthened interfacial bonding induced by MimMa. A modified interphase structure was accordingly proposed and related to the mechanical performance of the modified SBR/silica composites.

“…40 X-ray photoelectron spectroscopy suggests the IL cation interacts very strongly with the surface of the carbon black and carbon black surface area decreases by 30%. 41 In comparison, Raman analysis of carbon nanotubes in 1-butyl-3-methylimidazolium hexafluorophosphate show the interactions between the IL and the nanotube are very weak. 42 In these experiments, the majority of NEILs have thermal conductivities lower than that of the neat IL.…”

Thermophysical Properties of Nanoparticle-Enhanced Ionic Liquids (NEILs) Heat-Transfer Fluids

An experimental investigation was completed on nanoparticle enhanced ionic liquid heat transfer fluids as an alternative to conventional organic based heat transfer fluids (HTFs). These nanoparticle-based HTFs have the potential to deliver higher thermal conductivity than the base fluid without a significant increase in viscosity at elevated temperatures. The effect of nanoparticle morphology and chemistry on thermophysical properties was examined. Whisker shaped nanomaterials were found to have the largest thermal conductivity temperature dependence and were also less likely to agglomerate in the base fluid than spherical shaped nanomaterials. INTRODUCTIONIn many solar energy systems, such as concentrating solar power (CSP), there is a drive to operate at higher temperature to reach efficiency limits. This is often limited by the heat transfer fluids working window; it is desirable to have low temperature stability and expand the upper operating temperatures of the fluid. The current generation of organic heat transfer fluids, such as Therminol VP-1
