Implication

Experimental analysis demonstrates enhanced polymer-filler interactions for silica in polar nitrile rubbers, suggesting superior viscoelastic reinforcement relative to carbon black.

Key Points

To investigate the interfacial interactions and viscoelastic performance of silica fillers compared to carbon black in polar elastomers with varying polarity.
Measured the free energies of adsorption on silicas using inverse gas-solid chromatography with polar probes and n-alkanes.
Formulated series of acrylonitrile-butadiene (NBR) rubber compounds loaded with silica or carbon black across varying acrylonitrile (ACN) contents.
Evaluated the viscoelastic properties of the resulting elastomer composites to determine the extent of polymer-filler interaction.
Inverse gas-solid chromatography demonstrated substantially higher free energies of adsorption for polar probes on silica than for nonpolar n-alkanes, indicating stronger interaction with polar rubbers than nonpolar elastomers like polybutadiene.
Silica-filled acrylonitrile-butadiene compounds exhibited changes in viscoelastic properties driven by enhanced polymer-filler interactions relative to carbon-black-filled compounds across differing acrylonitrile levels.
