DISORDER-INDUCED ENHANCEMENT OF POLYMER ADSORPTION - A MODEL FOR THE RUBBER POLYMER INTERACTION IN FILLED RUBBERS

Various models for adsorption of polymers and disordered surfaces are presented. Such models range from certain weak random surfaces to frac tal surfaces possessing self-similar properties. Common to all models is that adsorption properties are enhanced compared to the adsorption on flat surfaces. The reaction for this enhancement is that the config urational entropy in the disordered case is less restricted compared t o the flat case where the chains become significantly non-Gaussian for large adsorption energies.
