The model is exactly solvable for realistic polymer models (e.g. the freely rotating chain and the rotational isomeric state models) and it readily accounts for inhomogeneities of the brush with respect to the plane parallel to the grafting surface. The interactions between neighboring chains is mimicked by the presence of a confinement potential centered on the grafting point of each chain. We explore the model to calculate the equilibrium and kinetic properties of the polymer brush. We find that the variations of the brush free energy and height with the coverage depend strongly on the stiffness of the polymer chain (bond angle) and on the severity of the chain confinement. The results for the growth kinetics of the brush are compared with recent measurements on the formation of a PEG2000 brush from solution. © 2004 Oldenbourg Wissenschaftsverlag GmbH Thermodynamics & statistical physics nationallicence Laboratory techniques, experiments nationallicence Physical chemistry nationallicence Livadaru Lucian aut Kreuzer Hans Juergen aut Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/8/2004(2004-08-01), 929-956 0942-9352 218:8/2004<929 2004 218 zpch https://doi.org/10.1524/zpch.218.8.929.35982 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/zpch.218.8.929.35982 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Livadaru Lucian aut NATIONALLICENCE 700 1- Kreuzer Hans Juergen aut NATIONALLICENCE 773 0- Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/8/2004(2004-08-01), 929-956 0942-9352 218:8/2004<929 2004 218 zpch CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
