Robust, stimulus‐responsive thin films are prepared by self‐assembly of diblock‐copolymer micelles from aqueous solution. Atomic force microscopy and fluorescence spectroscopy show that the hydrophobic polymer cores of block copolymer micelles adsorbed at high pH become localized cationic polymer brushes reversibly at low pH without micellar desorption (see Figure).
