In order to ensure better elastomer/functionalized Multi-Walled Carbon Nanotube
(MWCNT) compatibility and to enhance the dispersion, a series of ionic liquids has been tested in regard
to an improved interaction between elastomer and functionalized carbon nanotubes. We found that in
the presence of especially one ionic liquid, namely, 1-butyl-1-methylpyrrolidinium tetra
uoroborate, for
the hydrogenated nitrile elastomer, used as basic polymer, a 1.83 fold increase of elongation at break was
achieved with only 7 wt% ionic liquid loading. At this low concentration of ionic liquid the sample
can be stretched up to 508% without mechanical failure. The use of this ionic liquid additionally results
in high tensile strength (21.4 MPa) at low concentration (< 7 wt %) of ionic liquid. Energy-dispersive
X-ray spectrometric scanning electron microscopy con rmed the homogeneous distribution of ionic liquids
among nitrile elastomer chains by showing uniform signal belonging to
uorine in ionic liquid, when the
diffusion process of ionic liquid into nanocomposites was long enough (> 48 h) during the ionic liquid
absorption measurements. Transmission electron microscopic images confirmed the good dispersion of the
MWCNT along with the exfoliated structure of the CNTs in the rubber matrix.
