Here, the NIPS step allows for the formation of a highly\u2010permeable sponge\u2010like substructure topped by a dense thin layer exhibiting poorly\u2010ordered nanopores while the subsequent SVA treatment enables to reconstruct the material top surface into a porous monolayer of well\u2010ordered hexagonal perforated lamellae (HPL).

The post\u2010SVA treatment is also revealed as a powerful tool to tailor the thickness of the nanostructure formed within the blended material because monoliths entirely composed of a HPL phase are produced by increasing the time of exposure to a chloroform stream.
