CO2‐Induced Tunable and Reversible Surface Wettability of Honeycomb Structured Porous Films for Cell Adhesion

Abstract

Honeycomb-patterned porous films with different structures are generated from polystyrene-block-poly(N,N-dimethylaminoethyl methacrylate) using a breath figure technique. CO2-induced reversible surface wettability is then achieved by alternate introduction and removal of CO2. For the first time, original hydrophobic surfaces are directly used as scaffolds for cell culture with CO2 atmosphere to enhance the interaction with cells, thus resulting in better cell attachment and proliferation.
