N2 - Surface geometry effects on the adsorption conformations of polymers under plateau conditions are found and analyzed by using fractal geometry considerations. The re-analysis of many adsorption studies, with special emphasize on polystyrene, shows that while on a flat surface a dense packing is formed, distorting the solution conformation into a prolate shape, on highly porous objects the solution conformation changes only slightly upon adsorption. These general trends show a surprisingly low sensitivity to the chemical nature of the polymer-solvent-surface system, emphasizing the crucial role of environmental geometry in determining adsorption conformations.
