Single crystals consisting various surface morphologies and epitaxial structures were applied to investigate the effect of other phase regions in the vicinity of a given tethered chains-covered area having a certain molecular weight of amorphous brushes. Experiments were designed with more scrutiny, and the consequences proved that regardless of the type of surface morphology (patterned and especial mixed-brushes, homo and copolymer single-co-crystals or homobrush single crystals) and epitaxy of growth (i.e., epitaxial structures), for a phase region covered by a certain type of brushes, the respective characteristics were the same. Detection of participating phases was possible by atomic force microscopy (AFM) on the basis of quality of employed solvent in growth systems, interaction of brushes with respective substrate, stiffness, and crystallinity of PEG-formed areas. Hence, developed surfaces were not in need of any selective solvent to be detected.
