(A) Chemical structures of PEO45-b-PEHOx20 and PMOXA10-b-PDMS25: hydrophilic blocks (blue and green) and hydrophobic blocks (orange and red). (B) Surface pressure–molecular area isotherms of mixed PEO45-b-PEHOx20 and PMOXA10-b-PDMS25 at 100:0; 90:10; 70:30; 50:50; 30:70; 10:90; and 0:100 molar ratios. The values indicate the corresponding molar fraction of PEO45-b-PEHOx20 in relation to PMOXA10-b-PDMS25, and the arrow indicates the compression direction. (C) Zoom-in of the LC phase showing the curve shapes toward the monolayers’ breaking points with an inset image representing the trend of the chosen surface pressure values for the LB and LS transfers. (D) Brewster angle micrographs (BAMs) of PEO45-b-PEHOx20:PMOXA10-b-PDMS25 monolayer mixtures at 100:0; 90:10; 70:30; 50:50; 30:70; 10:90; and 0:100 molar ratios at the air/water interface at the breaking point and (E) local structure at transfer. The first number indicates the composition of the mixture. The scale bar corresponds to 100 μm. The isotherms were registered at least three times for each mixture composition.
