Relationship between surface hydrophobicity and solvent polarity.A:ET(30)values of solutions of PEG of varying molecular weight plotted over the relative mole fraction of PEG calculated as described in the section “Polarity measurements”. The slopes of the linear parts of the plots were used as measure for the polarity of PEG. B: The slopes as determined in subfigure A plotted over the surface hydrophobicity calculated from MD simulation results of the corresponding PEG molecules
