The influence of surface chemistry of carbon black on adsorption of oligobutadienes rubber

Abstract

In this work we have studied the adsorption of oligobutadiene rubber (synthetic rubber) on native
carbon black in comparison to heat-treated samples. Statical (batch) method has been used to determine isotherms
of adsorption. Experimental error was less then 3%. We found that thermal treatment of native carbon
black increases adsorption of synthetic rubber from diluted n-heptane solution. Obtained isotherms of adsorption
allow us to calculate distribution coefficients and differential Helmholtz energy for studied systems. In
comparison to native carbon black, heat-treated samples showed the higher adsorption performance due to
specific interactions at the solid-liquid interface.
