Abstract:
Polymer films with hierarchical micro- and nano-porosities were prepared by combining the fast solvent evaporation "Breath Figure" (BF) method, exhibiting a highly regular honeycomb micro-porous texture, with the additional nanoscale self-assembly of polylactide-block-polystyrene (PLA-b-PS) diblock copolymers, PLA being used thereafter as a sacrificial component for nano-porosity.
