  Improving toughness of ultra-high molecular weight polyethylene with ionic liquid modified carbon nanofiber

  摘要：

  Ionic liquids (ILs) with long alkyl substituted groups, including 1-docosanyl-3-methylimidazolium bromide (IL-1) and 1-docosanyl-3-methylimidazolium hexafluorophosphate (IL-2), were synthesized and used to modify the surface of carbon nanofibers (CNF). The nanocomposite film prepared by solution-blending of ionic liquid modified CNF (i-CNF) and ultrahigh molecular weight polyethylene (UHMWPE) displayed better toughness when compared with pure UHMWPE even at very low concentrations (e.g. 0.4 wt%). The effect of ionic liquids on the elongation-to-break ratio of this nanocomposite system was investigated. The ionic liquid with hexafluorophosphate as the anion was more efficient to increase the toughness of UHMWPE due to the improved compatibility of IL with UHMWPE in the polymer matrix than that of the bromide. The rheological behavior of molten nanocomposites revealed that the storage modulus and the complex viscosity decreased with increasing ionic liquid content in the high frequency region. However, a reverse trend was observed when the frequency was less than 0.05 s(-1). In-situ monitoring in the change of crystallinity of the nanocomposite during tensile deformation suggested a mechanism of sliding between UHMWPE crystal regions and the surface of carbon nanofibers.

• Ionic liquid crystals based on 1-alkyl-3-methylimidazolium cations and perfluorinated sulfonylimide anions
  作者：Ting Li、Fei Xu、Wei Shi

  日期：2015.5

  In contrast to the studies on ionic liquids based on perfluorinated sulfonylimide anions, their ionic liquid crystals were seldom reported. In the present study, four 1-alkyl-3-methylimidazolium perfluorinated sulfonylimide salts ([C(x)MIm][N(SO2RF)(2)], x = 18 and 22; R-F = F (FSI) and CF3(TFSI)) have been synthesized and characterized. [C(22)MIm][FSI], [C(18)MIm][FSI], and [C(22)MIm][TFSI] show smectic A(2) liquid crystalline mesophase. Single-crystal XRD revealed that [C(18)MIm][FSI] and [C(22)MIm][TFSI] show layered structures of low-polar and high-polar layers alternate with each other in the crystalline phase. It is suggested that perfluorinated sulfonylimide anions have relatively weak coulomb interactions with imidazolium headgroups, making them relatively difficult to form mesophase.
