Effect of water content in the HU layer (MW = 470 kDa) on the formation of porous textures in case of (A) pre-dried HU film and (B) pre-swollen HU film. Surface modification sequence was the same: 4 × 200 μL water doses and 40 × 200 μL doses of a 3:7 nBT/IPA mixture, dosing sequence 5 s. The surfaces were visualized using AFM (2D and 3D representations) and profile sections and analyzed for distribution of pores after the treatments in (C). All modification steps carried out at rotation speed 2100 rpm. Data from AFM.
