Following the kinetics of a chemical reaction in ultrathin supported polymer films by reliable mass density determination with X-ray reflectivity.
Numerous modern functionalities with ultrathin polymer films involve chemical reactions within the films. X-ray reflectivity can be used to quantitatively follow these chemical reactions by a reliable determination of mass density, which is feasible within certain thickness constraints (e.g., 5-17 nm thickness for common polymer films).
