Honeycomb‐patterned porous films with different structures are generated from polystyrene‐ block ‐poly( N , N ‐dimethylaminoethyl methacrylate) using a breath figure technique. CO 2 ‐induced reversible surface wettability is then achieved by alternate introduction and removal of CO 2 . For the first time, original hydrophobic surfaces are directly used as scaffolds for cell culture with CO 2 atmosphere to enhance the interaction with cells, thus resulting in better cell attachment and proliferation.
