“…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.

“…The non-covalent functionalization of HNTs external surface, with ionic liquids (ILs) was, also, reported. The interaction between 1-butyl-3-methyl-imidazolium hexafluorophosphate [BMIm]PF 6 and HNTs, proposed by hydrogen bonds, was verified by various spectral results and the IL-coated-HNTs were used as reinforcement for styrene-butadiene rubber [17].…”

“…[17][18][19][20] Previously, we verified 1-butyl-3-methylimidazole hexafluorophosphate as an effective modifier for improving the performance of rubber/halloysite nanotube composites. 21 This phenomenon is due to the hydrogen bonding between 1-butyl-3-methylimidazole hexafluorophosphate and the halloysite nanotube. However, most of the commercial ILs, such as 1-butyl-3-methylimidazole hexafluorophosphate, could not be directly used as the modifier for polymer composites because of their high polarity and limited compatibility.…”

A novel functionalized ionic liquid, 1-methylimidazolium sorbate (MimS), was synthesized and characterized. MimS was used to improve the performance of rubber/silica composites. Substantiated hydrogen bonding between MimS and silica was responsible for effectively restraining the Payne effect and decreasing the Mooney viscosity of the uncured rubber compounds. The reactivity of MimS toward rubber and its ability to hydrogen bond with polymerized MimS and silica were characterized. Filler networking, curing behavior, silica dispersion and mechanical performance of the vulcanizates were fully studied. Remarkable improvements in mechanical properties were achieved with only a small addition of MimS. Variations in rubber performance were attributed to the significantly improved silica dispersion and novel interfacial interactions induced by MimS.
