Average dry layer thickness of self-assembled, UV-immobilized PGE coatings B1:3 (blue), B1:1 (green), C1:3 (red) and C1:1 (orange) on PS- and PC- (a) as well as PET- and TCPS-coated (b) silicon wafer model substrates determined by SE. Horizontal dashed and dotted lines represent the start of the chain overlap regime (2R_f l⁻¹ ≥ 1) and the brush regime at which the substrate surface is completely covered by the polymer coating (2R_f l⁻¹ ≥ 1.4) under bad solvent conditions at 37 °C. (Error bars indicate SD; n = 6).
