[S36.039] Organically Modified Aero-Sol Gel Silica for Elastomer Reinforcement

S. E. Pratsinis (ETH Zentrum, Institute of Process Engineering, Zurich, Switzerland ML F 26 CH - 8092), D. J. Kohls, G. Beaucage (University of Cincinnati, Department of Materials Science and Engineering, Cincinnati OH 45221-0012.)

We have developed facilities to produce organically functionalized silicas using a novel, room-temperature, aerosol, chemical reactor (ASG reactor). This reactor can produce exceedingly high surface area nano-structured materials (up to 800 m2/g) with tuned interfacial chemistries.

This poster will present our results on dynamic mechanical properties of elastomer compounds with ASG-organically modified silicas and comparison with conventional carbon black, conventional precipated and fumed silica as well as blends of the conventional materials. The mass-fractal structure as determined by SAXS and SALS, as well as conventional gas and DBP absorption measurements and microscopy will be presented.
