How Pore Hydrophilicity Influences Water Permeability?

Figure 4

Three simulation models and the wetting states of hydrophobic membranes subjected to different hydrophilic modifications under ΔP =1 MPa. (a) Hydrophilic modification to the pore entrances; (b) regionally hydrophilic modification inside the pore; (c) hydrophilic modification to the outer pore walls. Green and dark grey represent the hydrophilic and hydrophobic part, respectively, and oxygen and hydrogen atoms in hydroxyl groups are marked in green and white, respectively.
