Nanoscale memory provided by thermoreversible stochastically structured polymer aggregates on mica

Stimuli-responsive polymers are used in a large variety of applications due to the controlled manner in which their physical properties can be reversibly altered. In this study, we demonstrate the thermoreversible structuring of poly-(N-isopropylacrylamide)-based polymer. By temperature-controlled a...
