Figure 4.

(A) Shift in phase (upper row, blue cyan) and height type (lower row, red orange) images of one-component films of PEO₄₅-b-PEHOx₂₀ and PMOXA₁₀-b-PDMS₂₅ and of 90:10 and 50:50 mixture films transferred onto hydrophilic silicon wafers in the forms of monolayers and bilayers. Imaged in water. Scale bar 1 μm. (B) Height profiles of the corresponding copolymer biomimetic membranes displaying height (nm) vs offset (μm). AFM measurements were performed for each membrane in five different regions and for at least three samples of the same composition.
