Adsorption of hydrophobically modified polyelectrolytes on hydrophobic substrates. Y. Zhang, M. Tirrell and J.W. Mays. Rev. Inst. Francais Petrole, March-April 1997, 52(2), 177--181.
A series of diblock copolymers, poly (tert-butyl styrene)-sodium poly (styrene sulphonate) with different molecular weight and percentage of sulphonation were used to study the effect of polymer structure on its adsorption behaviour onto hydrophobically modified silicon wafers. The experimental data were compared with scaling results and it was found that the adsorption of the hydrophobically modified polyelectrolytes onto a very hydrophobic surface is determined by the strong attraction between the anchoring block and the surface and the free energy of the polyelectrolyte brush which includes the osmotic pressure and elastic energy. 8 refs.
