| description | We present the study of millisecond-resolved polymer brush swelling dynamics
using infrared spectroscopy with a custom-built quantum cascade laser-based
infrared spectrometer at a 1 kHz sampling rate after averaging. By cycling the
humidity of the environment of the polymer brush, we are able to measure the
swelling dynamics sequentially at different wavenumbers. The high sampling rate
provides us with information on the reconformation of the brush at a higher
temporal resolution than previously reported. Using spectroscopic ellipsometry,
we study the brush swelling dynamics as a reference experiment and to correct
artefacts of the infrared measurement approach. This technique informs on the
changes in the brush thickness and refractive index. Our results indicate that
the swelling dynamics of the polymer brush are poorly described by Fickian
diffusion and the Berens-Hopfenberg formalism, pointing toward more complicated
underlying transport. |
