Reinforcement of HNBR By CNT

Rheological, viscoelastic, dynamic-mechanical and ultimate properties of CNT/HNBR compounds prepared by mechanical mixing in an internal mixer (1.5L) equipped with intermeshing rotors are presented using CB/HNBR compounds as a reference. The reinforcing effects caused by CNT are attributed to both the high aspect ratio and high surface specific area of the new type of filler. The largest differences to CB reinforcement are shown at small elongations and deformation amplitudes. Orientation of CNTs in shear or elongational flow leads to anisotropic materials with improved mechanical and electrical properties.
