Influence of long-range correlated surface and near the surface disorder on adsorption of long-flexible polymer chains

We investigate the influence of quenched long-range correlated surface and decaying near surface disorder on the process of adsorption of long-flexible polymer chains with excluded volume interactions on inert and attractive walls in the framework of renormalization group field theoretical approach up to first order of perturbation theory in a double ($\epsilon$,$\delta$)- expansion for the semi-infinite $|\phi |^4$ $O(m,n)$ model in the limit $m,n\to 0$. We obtained series for bulk and the whole set of surface critical exponents, characterizing the process of adsorption of polymer chains. The scaling behavior of the parallel and perpendicular part of the mean-squared end-to-end distance as well as the behavior of monomer density profiles near the surface and the fraction of adsorbed monomers are studied.
