The data are presented as averaged values ± standard deviation calculated from 3 repeated experiments both for PLL-g-PEG and CMD as well as for OWLS and QCM-I measurements. The superscripted indications are devoted to set the following remarks: ^asome referred data were not concretely measured on PLL-g-PEG and CMD polymers (see details below); ^bmeasured on PEG; ^cmeasured on PLL-g-D (D as dextran); ^dmeasured on dextran; ^emeasured on carboxymethyl cellulose (CMC).

M_A^OWLS: areal mass density measured by OWLS; M_A^QCM,S3, M_A^QCM,V: areal mass density measured by QCM-I and evaluated by the Sauerbrey equation as well as by the Voigt-based model, respectively; φ_A: hydration degree; $N_{H_{2}O/monomer}$: number of bound water molecules per one monomer unit of the polymer chain; ρ_A: density of the hydrated polymer adlayer; n_A, d_A^OWLS: refractive index and optical thickness of the adlayer determined by OWLS; d_A^QCM,S3, d_A^QCM,V: adlayer thickness evaluated by the Sauerbrey equation as well as by the Voigt-based model, respectively; η_A, µ_A: shear viscosity and shear elastic modulus of the polymer adlayer evaluated by the Voigt-based model.
