Abstract
The adsorption kinetics of a cationic polyelectrolyte onto a model negative ly charged cellulose surface has been investigated. Two regimes have been d istinguished. At low surface coverage, the adsorption is transport-limited while at higher surface coverage the incoming polymer experiences a blockin g barrier of electrostatic nature. This barrier has been quantified and the respective roles of the polymer and surface charge have been assessed. (C) 2000 Elsevier Science B.V. All rights reserved.
