Abstract
Carbon black is used in several technical applications. Fillers in tires,
black pigments in printing technology or synthetic cloth fibers are only a
few examples. Because of the small particle size of carbon blacks, the
surface properties have a great influence on the product property
. We
studied two different carbon black that show a large difference up to 20%
in rolling drag when used as filler in tires. Different roughness or diverse
polar groups on the surfaces are possible reasons for this.
Morphology, surface structure and chemical surface composition of
carbon black are not well defined. For such systems, TGA-MS and gas
adsorption are powerful tools to analyze surface properties. We use
adsorption equilibria in the Henry-region that reflect the interaction of
molecules with the particle surfaces. From measured Henry-coefficients
and known atomic surface structure, dispersive interaction parameters of
the solid, e.g. a Hamaker-constant, can be determined by inversely
solving the applied adsorption model. This method can be used to
characterize carbon black if the interactions of different molecules with
carbon atoms are calibrated on a defined surface like graphite. From
known interaction potentials of various probe molecules, structural
information like surface roughness of carbon black can be determined
