Figure 4
Cross-sectional SEM views of a PS-b-P2VP-b-PEO/PS-b-PEO monolith generated by NIPS-SVA (5 h, CHCl3) showing the DG structure in the vicinity of the (a) top, (b) middle, and (c) bottom film regions. (d) A top-view SEM image revealing the nanoporous morphology formed on the bottom surface. Inset: top view SEM image showing the double wave pattern produced on the membrane top surface and the DG structure formed within the blended terpolymer film. Scale bars: 500 nm.
